WOW Gold: Adding 1 point to STR or DEX if you have spare points
Stats: Most important thing is Intelligence, improving your buffs (except for Damage Support) and healing spells by roughly 1%/3.15 INT. Now, how much WOW Gold INT to have is dependant on you?
Some people get just INT and nothing else. Some add Dex to avoid some hits (although Blessing Armor is usually better).
Another good choice is to get some STR to carry slotted shield with good topaz *and* slotted wand, thus giving you even more INT (g7 topaz in shield would be +35, around 11% better buffs).
In short, get INT every level, maybe adding 1 point to STR or DEX if you have spare points. It will be quite a while before you have good topaz to insert into shield (putting +5 there is a waste), so STR might wait.
Minimum STR for socketed shield (round shield) is 36, so that would be enough (unless you use +STR items, which isn't really recommended). Also, SEN increases damage for Wands, but its effects are minimal, critical rate increase gives more damage than +atk from it.
For PvP, that would get mostly STR as secondary stat, both for extra HP and defence, as well as damage. Every little bit helps, since it might let you live *just* one second longer, which will be enough to cure yourself.
