Let me start by stating that English is not my native language, but I'll do my best.
I have a couple of questions about my char (can't post links yet, a shadow priest Fapperdefap on Frostmane EU) and how to improve more in pvp.
I used to play on a pve server, got bored with it, stopped playing for a while and decided to start over with irl friends on frostmane EU.
I've been playing around with the talents and glyphs to see what works best for me and got stuck with the current talents.
I use void tendrils in order to get some room while being trained by melee, Insanity for the burst, DI for procs and I prefer not to use halo (too random, breaking cc etc all over the place and the dmg and healing output is not high enough considering the cd).
Lvl 60 talent will most likely be changed to Spectral Guise, but I prefer Angelic Bulwark at this moment.
I reforge into spirit to get more hit due to being a human, plus having extra mana regen is never a bad thing in my opinion.
Then into haste / crit where possible and needed.
If there are any major mistakes I made, or other changes that could help me further improve, I'd be happy to read them.
