Picking the right talents is a big deal as disc. It sounds like you’re having some issues with 2 melees sitting on you, locking you down. If so, play twist of faith+masochism, along with ultimate radiance pvp talent.
Vs caster teams you can play b&s+castigation. And sometimes you may want masochism+castigation. Nowadays you’ll pretty much play ultimate radiance in every 3s game, and quite a bit in 2s as well. Ideally you wanna have the penance and radiance potency conduits, they help a lot with throughput.
When you’re struggling with cc and interrupts try to focus on your positioning, and dont waste too much time fake-casting. Its often better to be aware of which school interrupt is less punishing, and plan your casts accordingly. Sometimes you dont wanna get locked out on holy, as you wont be able to dispel. And sometimes you dont wanna get locked out on shadow, as you cant use shadow word: death to break cc, or in situations where you need massive healing and you dont have radiance charges available.
If you’re trying to deal with interrupts from 2 dps killing you, try to cast shadow mends first, use radiance–>penance when they kick you, then back to shadow mend. Its also very effective to use rapture and alternate between shield–>smend–>shield–>smend, to keep baiting their kicks.
You should avoid trinity until you’re very comfy with the spec. However if you feel comfy and you’ve gotten to the point where the need for improvement is in the mana efficiency department, trinity is a great talent!
- twist of faith when you struggle to outheal very often
- castigation when you dont have to hard-cast heals that much
- masochism when you’re the main target
- trinity when your main concern is mana efficiency and dmg is spread among 2-3 targets
