Warrior is dead, you can find some videos or advices, but it works against really big noobs, to be honest if you take 2 same skilled pvp players, warrior player will never win because of adrenaline generation, low heals, his important skills do 0 damage because of CC's and rest of skills are weak.. Warrior's main heal is ''number 6'', because you can't play without discipline (mobility, weapon swap and adrenaline), you need to take deffensive, tactic or strengh and there is 0 heal for dmg playstyle even after small buff MMR, so funny for primarily close combat class, you don't even have protection lol.. My advice ? Don't play warrior, it's unplayeable and PvP community is toxic af. Play necromancer, you can use only your head insteed of fingers to press buttons on keyboard and you will still keep winning..
Warrior is almost 5 years my main, 5700 hours, 2000 games in pvp and I've only visited plat.1 for a few times for a moment in last year. Playing necromancer ? Plat.3 ? No problem lol.
