Fighting an underwater bunker thief
you could do like I do and leave whenever the rotation gets to capricorn.
You don’t.
UW combat is still a mess and probably always will be, seems sort of pointless trying to balance it for PvP, you’ll probably just end up making UW combat in PvE even more unbearable.
Shadow Assault’s attack range is large enough to hit you no matter where you are on the point, so you’ll have to tank it if you don’t want to give up the point. Only options is trying to sneak in condition dmg, or retaliation, or condition procs when hit. Even then most thieves just use Signet of Malice and will heal nonstop with it to counter that.
UW combat is completely dumb. You will never win against that thief.
In all seriousness, I’ve beaten Thieves underwater with an underwater downed state Ranger, which is, in my opinion, even more broken. You just play normally until the Thief manages to kill you, then spam your skills until your #3 is up. You’ll regenerate a couple thousand HP per second and slowly kill the Thief when they run out of initiative. The only way players have killed me underwater as a Ranger is when they’ve outnumbered me (typically 3v1) and also had sharks – just being outnumbered or having the sharks isn’t, in my experience, enough to overcome the healing.
And yes, UW combat is dumb.
Main thing about Thief Spear, it’s a melee counter/evade machine. Probably because all but one of thief’s stealths (Hide in Shadows, 30 CD) are disabled in the water. I’m well versed enough in aquatic combat to give an sure fire method, but kite the thief with ranged attacks. Their Harpoon is way less threatening then their spear.
