Yeh I like this idea with the towers giving buffs/debuffs to the teams when you destroy them and it could probably be added as a Deathmatch mode, possibly BoA too.

I wonder how it should work if a tower is being attacked by both teams. If it should be given to the team that does the most damage or the last hit or something.

I would like to do something with player stats, normalise them in some way, but I'm not sure how I feel about it. I know in some games they recently changed their battlefield systems so that players only get a tiny portion of the stats from their items but it feels a bit unfair to those people that worked hard to earn their items - it also kills the need to earn points for battlefield items as they would be of no use anyway, so I'm not sure it's a good idea for this game. Maybe just for a specific battlefield, but not all of them.

As I mentioned in some other post, I think maybe some kind of ban system could work where each team can vote to ban something on the other team, like mounts, or transformations, potions, or possibly even a reduction to a certain stat, like reduce defense, or evasion, healing, attack etc. etc.

in the games ive played the tower is usually activated when your team is in the zone of the tower for so many sec. the other team can come kill you and take over the zone thus giving their team the buff.
i think for iris when a team kills the tower it respawns in like say 20(give or take) sec and if other team comes and destroy it buff goes to them. as for last hit or most dmg i think most dmg would be best but the towers should be fairly easy to kill (not like boa) to begin with and respawn quickly or the map would get congested at only one tower spawn making the others useless.

and yeah i like the ban idea
