Other useful stat sets than berserker?
There’s sinister for heavy armored bosses solo, and assassin to mix with berserker when you lack precision. You can also have 2 berserker sets with scholar and strenght.
You can try a mix of Valkyrie and Knight. The first grant you Vitality+power+ferocity; the second grant you Toughness, power and precision.
With that mix you can be defensive but with a good power, precision and critical damage.
Or at last you can mix Soldier and Berserker stats to obtain a more defensive build.
But in PvE (expecially) for the 80% of the dungeons you don’t need defence because if you’re a warrior everyone want you to be a berserker mindless dps with GS and Axe/Mace.
There’s a large amount of viable builds for the warrior, good support builds, defensive builds, hybrid builds, condition damage builds, but no one cares about that because in PvE everyone want you to deal damage and no more, because there’s no need to be tanky if you kill your enemy befor your enemy kill you.
In WWW you can become more useful as a Shoutbow healer with condi cleaner, but no more. Banner regen don’t work in WWW and there’s only few things that can make you useful because the warrior haven’t good defensive buffs (and can’t give them to allies).
Then, you can use a Shoutbow variation with sword/shield instead of sword/warhorn and hammer as a second weapon. But no more.
You can try to be a stunner with full Soldier/Sentinel equipment to be very hard to kill, Hammer, Stomp and Fear Me!, (adding that un your Shake it Off! to obtaining heal and condi clean from FM! and SiO!).
