This isnt even considering pvp or wvw. This is just purely pve thoughts.
The class is a shell of itself these days. All 3 of its elite specs are dps specs and none of them are even top of the charts. Support warrior is a terrible healer, and bad boon support. Banner change is a joke pulsing boons every 3 seconds is hilariously terrible when you take into the fact that all the boons pulsed from banners are going to be pulsed from other allies in a higher duration as an afterthought in most builds.
It's had its power coefficients cut, its damage modifier in trait lines nerfed, the class has 0 teeth. Granted everything is viable in pve but still. Why play warrior when you can play a mechanist spam 1 with a mech, have 25 stacks of might, quickness, alacrity and fury 100% uptime than have to play a dps build perfectly to even come close to dps like this? Why take a warrior now; even before the banner change warrior was a niche slot because another DPS character could have filled that spot and made up for the loss of damage from banners anyway.
The class needs serious help by either giving them actual support capability, its only team supporting weapon is warhorn which is 2 skills in an offhand. Or given some of its teeth back so its not just a paper mache tiger. The class doesnt have the tools(weapons) to heal allies or support them as much as anet wants or thinks that warrior does, even the traits that effect your allies for warrior arent even all that great.
Just a stupid idea in my head to give warrior some teeth? Give it back some power coefficients.
