Thanks for your answers.
Perhaps my strat is not good. My App is 400/700/400/400 with low DPS. So i have to switch with my DPS Hunt, but i lose 30% of my towers stats. I can't pass last wave of Alch Labs in NM, my towers don't have enough HP. So i guess i can't try survival...
I can do NM ES HC, why not... I can try Misty too, but spiders eat my towers too fast... Maybe i have to find a better build.
