i just can't decide which one to pick any sugestions

I'd like to know too.

I (fulll wis priest) once disconnected outside Fury gates, and when I logged in a couple hours later, I spawned in the same place! A lone pagan was running down towards me and I started running away... then I was rooted and stunned for about 10 dmg (I have about 2k hp), and his other attacks did 3-5. Should I have stayed and fought, assuming no other Fury would join in?

Skills like Magic Mirror are good for situations like that. The difference between the two is simple. Support or attack? Priests and Oracles are normally counted on for support, while Pagans and Mages are counted on to deal damage.
