Thanks. Since I only have stamina for two master runs, I will try some experts then.
Master/Legend is not that difficult if you have Cu Chu+ Droid dragon + ADKZ. Carefully stall on the first or second floor, bursting through floor five using two orb changers and mass attack, stall on floor six again. On floor 9 use Cu Chu+ADKZ. Floor 10 = use droiddragon active.
I'm down a Cu Chu and ADKZ (although I do have an ADK), so that's out of my league right now.
I really need to focus my next efforts on putting together something to get a Hera. She'll be a great start to having me feel like I'm actually making progress in the game again.
