U have a great game but can be better;]
1. Hope u plaining add live pvp.
2. U should add hero with power to intterupt combo. maybe smth like: when u use 3rd time hero skill he can reflect damage(it should balance infinity combo with ragnarok, storm......)
3. Tournaments needs rework. I read this not one time, why they are 4 or 2 days long, when important are only last 2 hour. I dont even say u have customers in europe....... not only in usa time zone;]
4 sp event is great pls do more ;]
5.add boss battle, survival mode for extra iso

Sry for my english ;]
