I really think we should have something to unbound gears!
I wouldn't mind if it costs energy.
In my opinion these should be the rules of unbounding to avoid abusing it:
-Unbound will cost 20 Energy for 0-1 Star Gear, plus reseting the item level.
-Unbound will cost 50 Energy for 2-3 Star Gear, plus reseting the item level.
-Unbound will cost 100 Energy for 4-5 Star Gear, plus reseting the item level.
-Once you unbound, equipping it will make it bound again.

The game is getting a tad repetitive, I'd like to suggest a Quest System.
Quest Systems should be related to dungeon enemies, and certain quest NPCs should appear at the starting of certain dungeons.
There should be 3 types of quests, as do other online games:
-Story Quest = As you progress through the game certain NPCs will give you quests.
-Repeatable Quest = NPCs in fixed dungeons give you a certain task to destroy certain amount of enemies/ collect certain quest items (not mats).
-Daily Quest = Quests that only appear daily, they should be challenging yet rewarding.

personally i really like items that binds on equip. it comforts me knowing that some epic weapon with a great UV can't just be passed down from people to people like some kind of family heirloom. prevents people reselling it for cash, and i think it is just elegant overall.
but a quest system would be great! i would love to see things like, "the number of fiends has exploded, kill X number of them" or some kind of quest mechanic.
