OP is right. The amount of arc dodging in the game right now is ridiculous.
It used to be a skill to plan ahead and try to guess/outwit your opponent. Now just take a phantom, use a 2 bank 90% of the time and call it a day.
Wave 4+ is far less tactical and way more about list buidling because of it.
(My opinion of course)
I think you nailed it. There were more and less effective builds in Wave 3, but list building was a bit less important back then.
The 1 turn actually finds more use on the Phantom i believe XD
