balancing your char to your needs is the best you can do.. for example.. my best playing days were as rogue.. i am a minor whore (spending like 20 hp pots in 2 hours or pk) so i always wanted big mana pools.. ap wasnt a must for me.. used to be pking with 1.4k ap (PRE ROFD days) and 4k+ hp on lvl 67 rogue..

when i was playing priest (always as BP) my goal was also the shitloads of HP(dmg always comes enough as debuffer) so i used to have a combination of hp/str jewels/gear

balancing the char to your needs is always the right way if u cant have TOP class items
