Rifles with ranged speed + ranged dmg + dex (dex users are picky about rifles) + stun.
High melee dmg gear
We aren't picky, it's just hard to get a decent rifle that's worth enchanting
, so if the basic stats don't include +ranged damage and some ele damage and either dex/wis/vit, the chance to get a nice rifle by enchanting is quite small
Btw - maybe some good advice for low lvl yellow stuff: sell at AH, high lvls will buy in order to dismantle it
