1 positive is that mages can't solo/group AoE porta/krator's anymore, you didn't even explain how it would be a disadvantage to you and how can you seriously compare with official when they've left summoners and tanks in the dark (bring little or no use to parties).
I started yesterday and i've very impressed, I played 4game's classic eu for a month recently and the active population on here looks over 5 times more at least!
