int since it has been said like 100 times that INT > SPIRIT if you are hitcapped from the spirit.
Spirit does a shit to our manaregen, Int is mana spellpower and manaregen.
Staff vs 1h/off
- 33 int
+ 9 sta
+ 0.4 wpn speed
i would go 1h/off becaue imo almost 1% crit and 33int are better than 9 sta n 135 spirit, tho you can reforge that extra spirit into haste, making it almost as good as 1h/off for druids.
