Please note:This is only my idea for the new update.
Why don't we buff the old monsters like change their stats and traits like Uriel. Bad traits and stats, and he only has one great skill "Holy resurrection" with 60 stamina and 6 turn cool-down. So why don't we buff him like this "Holy Resurrection" with 40 stamina and 4 turns cool-down? I mean like do you want to get a Legendary monster that has more than 60 stamina cost and 6 turns cool-down? (Except for the Timerion) Uriel has the potential but he just couldn't do it. He could be the best support Monster but he just can't do it.
