1. I don't get the Enemy Forces: Wave 1 Icon. Why is it needed anyway? Besides that it doesn't change name/title into the current wave, you could just do it simply with a leader/multiboard.
2. How are you supposed to stop the dudes with Divine Shield?
3. Where are the lives stored, so you'd know how much you have left without counting? Never mind, I guess, since, you can see the gate HP.
4. Max Winter Storm's icon doesn't look passive like the other ability max level icons do. You can use this program to make it passive in case you don't have such a version.
5. For some reason the 5th Grand Admiral is basically immortal. His regeneration is off the charts. After reaching the middle of the corridor which took some good minutes, he was finally killed somehow

But the 6th.... is just time waste. Luck rooting and freezing him cuts his regeneration power, well, until he almost reached the end and gained full HP in a matter of seconds... and defeat. Weird thing is, at this point, I had all upgrades and tower types and slots filled with towers that could reach the enemy.
6. Why no Thrall builder

? You could even make a Chaos Grom (skin) secret when choosing random. Maybe even add Vol'jin and Rokhan?
This time it didn't crash but started lagging like heck between Paladin-Jaina waves.
I guess, I can
approve this but it still needs tweaking.
