So you are saying the problem with Warriors is that they do not do enough damage? <- is directly related to gear.
I'm saying that mages are more useful because they are more useful. I am saying that warriors are less useful because they are less useful. If warriors could cast heal on teammates or could fly, they would be more useful. I am not saying that "more damage" is the only solution to warriors. In fact I would prefer that there be no damage buffs, only nerfs, because it is already too easy to do perilous for people who know the best strategies. Most of those strategies of course involve no warriors.
Legionnaire is a tank and isn't meant to do damage. He is meant to take damage. Even still - Payback strike is AoE, Shield Bash is AoE
Sadly the best way to make enemies do less damage is to kill them. This has been a big issue that many games don't really solve. REAL AoE, like the mages have in this game, is usually king at end game in most games with warrior/rogue/wizard, and it is little different here. Legionnaire is decent in routine, not so good in threatening, and... he's a funny rollypolly in perilous.
Templer - Wrath of Heavens > Dispel = AoE attack
It's decent, but very long cooldown and not so large radius
Katari - Mighty Blow is AoE, Earthshaking Strike is AoE, Whirlwind is AoE. basic attack is AoE
Small AoE. Whirlwind sucks. Basic attack in threatening and perilous? Hahahaha...
Reaver - DPS machine and will become a mainstay of speed runs. Dragon Rage is AoE, basic attack is AoE.
Reaver is good, but it is much riskier than ranged classes.
The current problem with warriors on Perilous (minus Legionnaire) is that HP and melee/range/magic damage resistances are not high enough to allow warriors to get in range, safely and consistently.
Even if a warrior had as much survivability as a ranged character casting spells or plinking away at melee enemies 20 feet away, would they be able to do as much dps as a no target cap barrier-buffed immolation? I still think the main issue is that AoE is king in this game. There are many ways to go about fixing the issue,
Sure, the best combo in the game and a ability that gives everyone 35% damage is useless.
Templar combo is pretty good, but it's not perfect, long cooldown, small aoe, and doesn't work on CC immune enemies. The 15% damage reduction and 35% damage horn is not that great because it has short duration, long cooldown, long animation time, and makes you have to remove either blessed blades or shield wall. I don't want to remove BB because it is good for spamming more combo, and I don't want to remove shield wall because I like not dying.
Shhhh, let them think that throwing around 500 damage ablities every 8s is the best dps possible in the game. Just like the guy who posted that he was able to solo threatening level 5 with a lvl20 elementalist - in 10 minutes lol...
Immolate with barrier buff can be well over 2k AoE damage per cast. Have fun lying to yourself and everyone on the forum.
Conclusion. No, two-handed warriors dont suck, it's a l2p or get good gear issue.
2Hander is harder to play than just staying back with the team, sharing barriers, and nuking everything while enemies try to run to you. It might be possible to play 2hander decently in perilous, but the question is, why would you want to do it? You might do it for chests or for fun, but I doubt you'd do it because you thought that it was better than mages.
