Bowzon is not in good spot. The Wyrmshot is just weak, you need like bis end game gear to make Bowzon works. Barage is useless with short range, there is Stormcall with much bigger range, barage is such as fun skill its shame we cant use use with max range. Trinity arrow aka boss killer does some damage but is so lame and slow Overall Bowzon is just so weak witout bis gear as a result noone play it, there are like 5 bowzons only out of 100 in ladder. Her passives are mediocre at best compared to other classes. The 0 defense buff is just annoyance, she has not much armor anyway and die in few shots from everything making gameplay more annoying then fun, one mistake and you just die. She has no summons or anything for help. I am curently at duncraig with Ice breaker bow and the damage is okish, but the flamestrike spam from bow is so annoying cant see the barrels, I wish the flamestrike would get replaced with something like apocalypse. I also have Windforce bow and I think the damage is bugged it shows less damage in sheet imho maybe it does also less damage then it could.
Paladin unholy caster is in good spot, really feels good and is strong even with mediocre gear, few ornate shrines and you just rox. Great passives and tanky summons, triple damage compared to amazon with similar gear. Only negative is the slayer, its like full useless and does literaly almost zero damage even maxed, the animation is long before starting doing damage, previous version, when you could cast multiple slayers was much better. Does everything fine even fautz.
Barbar Earthshaker, Eartquake is good really fun skill with decent damage. Shower of rock has good damage but the cooldown should be removed. I had no issues in dunc but he is so weak in fautz against necrobots, I had to respec to guard tower, which is shame. The removed cd from shower would help against necrobots a lot. Overall fun character but need some buffs for end game, until fautz he was like godlike.
