My question is after getting to lvl 18 on mine, is this toon pretty fun once your 30+ for pvp or pve? What stats do you focus on for your gear

hp in your gear, nothing affects healing. mboost if you want dmg, but you'd be better off boosting your hp.
conc, macc as secondary stats i think. your macc takes a dive when you switch to mace/shield. staff's good for pve leveling/ganking though.
they're annoying to kill in pvp 1v1, but not exactly powerful in terms of sustained dps. not bad not good, but awesome support + survivability.

Focus all on HP, look for concentration too if the item already has HP on it.
I'm level 31 at the moment, easy to kill in PVE, hard to kill things PVP but not to difficult to stay up.

Currently lvl 34 and don't have to many issues can hold up against a group of asmos and walk away. Pve i use staff and pvp shield and mace other wise i can out heal most damage and still get good killing done
