If folks find them unbalanced-ly hard they can be nerfed (probably by making them also slow-die), I had just gotten the impression that they weren't overpowered as enemies, just annoying.
Alone they are not so bad, in packs of 10? They ripped my 600+ man fleet and 1 fortress easily
.
This was somewhat early game, but I had mK III bombaers and fighters, and other units as well, not at max cap since I hade been fighitng a lot. They are indeed annoying, but also very powerful if you do not blob them and kill em quick.
Btw, I notice some wierd logic in them form time to time, like they have conflicting orders.
They would move a bit towards my WH, then a bit down, then towards my WH, then a bit down, almost like they where reciving new orders all the time (or ratehr, reciveing the two same order over and over again).
I have recently noticed this in my units in FRD mode as well; units head towards the enemy, then a bit bakc, then more towards teh enemy, then a bit back (and now no longer all the units engage in comabt in FRD mode)
