I've been playing since day 1 and am loving this game still. I love character building and I love marvel and this is just a ton of fun. My only complaint is the ISO bonus. I had no clue about changing it until recently to get bigger and better bonuses. I understand that it is my fault that I didn't know about it, but I didn't. Anyone after spending a million in gold before the update I just spent 200k and finally got an 8 ISO bonus for my main character. The crystal cost to remove ISO is a bit steep, especially considering That we have no control over which bonus we get. I have a 6 star DD and had accidentally already had 8 ISO equipped which would have given me one, but the bonus I wound up getting cost me 600 crystals just to swap out ISO. I just wish once you got a character to level 50 and opened up the last ISO spot it gave us the option to remove all ISO cheaply as there isn't a way of knowing which bonus you'll get.
