How do you survive??i feel like cannon fodder from all classes,i can get kills etc but it feels like you have to have a good team to do good or you dead right away,necro dots crits are insane and assasin kill me in 5sec with no chance to damage him?
Stay close to the team, you're after all not e.g. a guard that can do their own thing solo without getting one/two shotted.
Primarily protect healer (also easier to get heals then) and ranged, it will also make it easier for you to one/two shot e.g sins that attack those people.
Try to often use CCs to help your team, not just to farm poeple. Also fear is awesome when someone tries to pickup flag (without shield of the risen ofc) or when you're not focused and can save your healer/flag carrier.
Kite, kite and kite some more when needed.
Use molten flesh wisely, phoenix when you don't need to move too much with its snare (and no enemy necro around) and don't forget cold protection when facing necro (it's not just unholy dots from decent ones).
Molten Flesh is awesome, so many noob demos that will mindlessly waves of flame and heal you back up to full HP
But yeah, HoX is mostly a get in and get out when you start getting focused class, the big thing imo is remembering to pull out of combos if you have to. Better to lose some damage and go heal up than to die because you wanted to finish the HS combo for example.
As for perks, from the beyond is really good, or the Pillars stun is pretty handy also. Red Shadows provides no use, PoT is average at best.
