Buggy
So far the game is generous with energy, but terrible drop rates on leveling up items; I suspect it's around a 5% drop rate on most items. Unfortunately, the game is filled with bugs. I have four rewards I can't claim and they won't go away. Also, in some matches, my heroes continue to stay paralyzed even after the counter reaches zero, making their supers unusable and I lose matches (especially when they have counter on). Also, it's a bit ridiculous that there's dozens of heroes, but since downloading the game 3 days ago, I've gotten copies of heroes a total of 5 times. Seriously, there's dozens to get ... and your game continues to give me the same ones I already have and then converts them to LOW amounts of gold when I spent 300 gems on the roll? The auto-battle definitely needs improvement and the ability animations take WAY too long (give us an option to disable them?) If they fixed these things, I would give it 5*.
