Yes, yes, minus the hero, I'm using "that" combo. I want to switch things out when I get enough XP to make Boomerang not ass though. Heli looks fun.
I didn't play BTD6, so learning to deal with the new additions was a challenge (namely purple and ddt.) On the other hand, this is a huge step up from the first game, and seeing power ptwshit and the awful ranking system cleaned up is making thing significantly more enjoyable.
On the other hand, some towers are WAY too OP, and need to be balanced out yesterday. Off the top of my head, Tack, Rocket Dartling, and Kraken Obyn. It's not bad enough yet to make the game completely unfun, and I do think that extremely carefully designed OPness can force people to change up their strategies (see first game as a negative example, rainbow rush = win 99% of the time) but the current state of things is definitely busted regardless.
