Don think it is wise to spend real money on this game since RoS is coming soon..
You going to see all those gear that we're using currently is going to obsolete..
But if buy gold to buys mats for crafting thats a different story..
Buy those legend plans like seven sin,.. Buy those gear plan that don carry ias, cc or chd..

Cause in RoS you going to see a huge boost on main and sub stat..

Seven sin property (might be)
5xx main stat
3xx vit
2xx sub stat
