They should do an event where a player designs a piece of equipment that would be implemented into the game. Like for example(just making this item up as I go)
When there is a create your own gear contest you have to
1. Come up with an image of the gear you'd like to be implemented
2. Can't be totally OP
3. Then people vote on the gear they want to be implemented like for example
4. Where it drops
Broadsword Of The Leech(one hand sword) Lvl 30, base # str
#-# damage # speed # bonus stat
Bonus effect like since it's a "leech" the effect would be steal 5% health from total damage dealt(aoe included)
If aoe skill does 100 damage to 5 enemies then 5% of 500 would be heal 25 health
Reward: winner of the contest gets one of the item in game
