I've been playing the game on flash back then. I'm glad they added a lot of things on mobile like new units and unit upgrades. I've seen the unit statistics thread and there's really a lot of changes on the damage of turrets like how Nyon Exists were like the best go to in flash but Cold Phasors becomes the dominant non-rare turret in the mobile and how Korazons are a lot less powerful while Zakana G's are strong shieldbreakers.
I was wondering if what are the best units you should be keeping during endgame or if farming in hard and insane difficulties? I always keep the rare laser units (aries, valerion, lightb) as thr main damage powerhouse with a pair caligo nox, wasp, and minor turrets. I wonder if I should get a pair of elson terra and poseidon?
Also, how viable is keeping shield generators? They are number one the most fragile of all my units since they get instantly fried if a shielded enemy reflects back laser to my shield gens.
