I think you guys, complaining about the 1h + shield build on the warrior, are getting it wrong.
You have some presumption that this build should be a slave damage sponge for other classes.
Maybe you are getting it wrong.
The 1h build maybe just excels in being survivable on its own. Yes it can't dish out the damage a 2h warrior can, and that's how it is logical to be, 2h warrior - the brutal damage dealer, a cultural thing if you want, it doesn't have the aoe of the mage, logical, but it has the highest survivability while being in the fray of the battle.
If you want a walnut that won't break while other party members try to survive there you go 1h + board.
being defensive doesn't mean you have to die for other party members, it could just mean you are tough on your own and don't need so much other party members to help you while you do your thing, chopping bit by bit the enemy, applying CC where needed and so on.
Just don't apply your MMO mentality here.
Maybe if you want a glass cannon mage that dies when spit on, you shouldn't expect your 1h + board puppet to defend you - just rethink your mage maybe? Or try another combination of skills, that gives the mage a little bit survivability on his own.
