Please pardon my ignorance but why would you need such buff?

Is there dungeon that is not beatable with current gears? Let me guess, Catacomb, isn't it?

Oh well, if you want to make IDQ doable for 1x players, then your suggestion might be a good idea.

Drop rate is too good at the moment now, loads of unused items sitting in inventory/warehouse. Hit may be an issue, but crit is not. Oh hey, you can easily reach 350% hit, I'm wondering why you need more than that. Bunch of stackable debuff and food/pot, 0%cd on healing.

I'm seriously wondering if any dungeon out there actually stands a chance against an end game party/raid. As far as I know, nowadays, difficulty comes from player's stupidity and lag rather than the items/buffs themselves.

i think this is a good idea, cause it only works when u have party on the same place also i remember one time when we killed glac loots was all yellow >.< .. also it will give buffs for some newbies who will join the game..

I like the idea of party gain buffs when youre all in a map. Perhaps EXP gain instead? Or if it needs to be a stat, maybe just one lol.

Passives for having people in a map is a bit overpowered HAHAHA. Think of all the alts.

im forgot to add the EXP Bonus DX
well if its come in Scale Raid yeah it was OP :v
but since raid comes in 3 Party
it should be max at
Drop rate +18%, all attack +300, all Defense +1800, Crit +120, hit +120, and all stats +120.
but if it was too OP maybe 10 All stats for each member would be good? so max would be +60 instead of +120

Actually, catacombs have been cleared many, many times before. And we all lagged like hell, but we did it.

The drop rate and stat boost here is actually really good to run GTI, TOAI, and IDQ with.It'd make running the dungeons a lot easier, and more rewarding. It would be especially important in cases like this here because in GTI, the worm-worms drop food materials that are essential to run dungeons/raids with (ie worm worm legs, which are used to craft - aggro).

In IDQ, the hit/crit buff would help newer and less-geared characters run the dungeon. For instance, if your tanker has a lower hp and def and cannot tank CI without a proper healer, the party system buff would definitely help her/him out in case the healer is not that great either. For the dpsers can't kill that fast for the tank, the boosts would be of help also.

By the way, the recommended hit rate for end-game things is 380~400%--not 350%-- which is harder to reach for non-dps classes like Templars . So if let's say we go IDQ, a hit and crit bonus would help them hit the boss and mobs more efficiently.
I know this because I have a tanker character: you always lose aggro (and end up killing the whole party in most cases) without a good enough hit chance or/and not enough damage to keep aggro, which often comes from the situation where you're not properly carded or geared. Again, in cases like this the benefit system would help a lot: more crit = more damage and more hit = more hit landed on the monster(s).

This brings me to my next point.
The difficulty of clearing dungeons doesn't necessarily ALWAYS come from stupidity and lag; it comes from items too. You can know the mechanics, have a party made with well-equipped characters ...but it only takes you so far without the proper consumables.

If you don't have the proper food on certain dungeons (for example, players with high-damage snipers-that know how to use them well will always need minus aggro, even if it is a simple 3 minute dungeon run like Lisk H) you WILL end up having things go the wrong direction because the boss starts loving the dpsers instead of the tank. And how exactly are you going to kill the boss when dps keeps dying instead of damaging the monster(s)? Especially in dungeons like Lisk I where you get locked outside near the gate unless someone revives you?

...and pardon me for saying this, but the drop rate is not enough ;-;
I know I may sound a little whiney about this since I know this was made to be one of the harder things to farm but...
Powdered owls eyes, man. For that +120 stat food it is sure of a pain in the butt to farm. Worth it, but a pain still.
Like I'd totally kidnap all my friends and camp in PI for a bit with them to farm food mats if this ever gets implemented. *^*
I mean they're easy to kill but one time I killed over 40 and not even one dropped... T^T

Finally, what are you talking about by how this idea supposedly makes "IDQ doable for 1x players"? IDQ stands for insane dungeon questing, and I highly doubt this party benefit system will boost a character's stats to an extent where we have an almost equal stat to the GM titles and can suddenly solo a dungeon made for 6 people in 15-30 minutes ._.
Like, good luck soloing TOAI under 30 minutes! Those fish hurt like hell.

I thought this buff wouldn't help solo players.. so I don't see the impact on idq? O_O well if he means from the perspective of encouraging more ppl to party up that's nice I guess.

A Buddy system....

Asking for prophet/saint buffs must be hard now so partying to get buffs must be added and look at the stats when it adds up to prophet/saint buffs.
I want to see this especially on one class parties like gunners/casters they benefit the most in this set-up.
I want server buffs added to this too cuz maybe some people miss the stat giving server buffs, we rarely get them anymore I wonder why

sarcasm doesn't work for everyone *sigh*. My point is, and you confirmed it yourself, don't make the game easier than it already is. Private server has tendency to make thing easier than retail in order to make players stay, but in the long run, it hurts them more than it helps. Some of you may say "I still play because I wanna hang out with my friend", but many don't think of it that way. As soon as a person finds this game non challenging, they will look for something else. Believe it or not, the phrase "hang out with friend" is just an excuse to go online and check if something new is added, or rather to join a raid/party for dungeon runs.
