Return of Reckoning

Hi all, after some time of trying some characters i fell in love with the Witch Hunter. I'm a noob player , i used to play Choppa on the Age Of Reckoning server so i'm an old player but not expert at all.
I'm just her to ask to you Elders of the Internet cit. a complete guide to the Hat .

Love ...

I would like to play an Order healer as my main character, of course it will be spec as an healer and nothing else. What do you suggest in order of priority ?

So Runepriest is the best healer, Archmage is good but requires a certain knowledge , Warrior Priest is the most difficult to play well and even so it's useless for the group if RP or AM are available.

Can i solo with warrior priest for leveling ?
Can a Warrior priest survive 1v1 ?

Thanks for reply; what do you mean for most rewarding ?

Hi everyone, i would like to know, according to the elders, which are the most difficult healer classes to play under the aspect of leveling and RVR.
Thanks

P.S.
I'm a beginner and i would like to choose a healer in Order, i would like to pick one of those

Hi guys i know this is not a solo game , but if i match an archmage in rvr with any of my greenskins do i have ahy chances to bury him ?

how can i check mine ? cause i often lag .... thank you
