crusaders as for human terms can be pretty good if built right and played right, vanquisher no matter how you put it are pretty much useless, yes they being hybrid have high attack but crusaders aren't far behind, and as for skills basis, vanquisher are just terrible, when the ITD was 100% bugged they were gods, still killable but damage wise was amazing, they had found their true calling but! when the ITD was fixed which needed to be done, zerks (2nd class) vanquisher 3rd class, became useless why? you ask... their ITD is maxed at 30-50% on their skills they have many ITD's but the damage from them is low since its been fixed,
and if you look at their skills cooldowns they range from 20-45 seconds for the ITD skills others are like 10seconds which is still annoying tbh, in that time a merc or SB could of done whole skills bars 2-3 times over RDPS could of glitched your ass to death before your skills are half ready, eva kind would of spanked you in seconds with 1001 debuffs haha, anyway vanquisher would only be maybe MAYBE decent if you fully all stat VI'd it full pvp access pvp cloak etc etc but even then youd need time to learn to play and time your buffs cause if you miss time stuff a lot can happen in the time it takes for your skills to come off cooldown most likely youd die if you don't just run away but then do you really wanna have to run all the time so yeah,
