The 5500 item is total shit for its cost and needs to be reworked
In the beta it was cheaper and better - way way too OP and overused.
Heart of life needs to cost 12k and/or have a substantial increased cooldown.
Maybe increased cooldown but:
1. It takes up a disposable item slot.
2. Cost a good amount
3. Good players can stop the enemy effecitvely healing
4. HP/Mana pots can be just as effective, if not more as they can be used mid-battle.
But yea, it is very good- but its not OP, so I think they should keep it.
