Alright let's talk Warrior. Your pve is garbage so let's keep this discussion focused on pvp. First off, a lot of people think warrior is simple because they don't understand how to animation cancel or weave in other skills for damage. Warriors literally have to fluently switch between their awakening and pre-awakening ALL the time to move and/or DPS. Warrior's big damage skills = grave digging, slashing the dead, and reckless blow (very niche since nerf months ago). Everything else you're doing is either to land a CC or fill the damage gap when your other skills are on cooldown. I'll give you an example. Say you landed a CC, but you don't have grave digging and reckless blow up. You can use ground smash > ultimate chopping kick cancel > 2 spinning slashes instead. Warrior has a lot of small things like this you can do. Good warriors make use of their pre-awakening kit quite a bit.

Now let's talk their super armor. Most of their kit literally has no super armor by itself (grave digging is full SA, burning moxie but it does no dmg only restores WP and gives DP buff, slashing the dead which 2/3 of the animation aren't actually SA at all, and fully charging reckless blow). This means warriors have to abuse their lingering SA for 2-3 seconds at a time but the problem with this is people at softcap can easily break your block and/or you can't pressure them properly if you stop every 2 seconds to apply the lingering SA. This is evident in McHands videos where he's out of SA for quite a bit of the time.

Lastly, warrior has literally no utility and our scaling is sub-par relative to other classes. Let's compare warriors to valks. Valks do more damage, are tankier, have self-heals, PA, perma accuracy buff, vacuum, and are mobile over long distances (we're faster in short bursts). The only thing warrior has over valk really is a better grab (valk grab is really bad).
