They have the same speed as LEV tanks, not sure why people are saying they are too slow.
I think the main problem with it is that they cost almost double of a LEV tank but they obviously dont do similar damage and they have a setup time for no reason.
The main attraction of higher strength for melee is that they take significantly less damage from attacks and getting more melee units into position is harder.
This doesnt apply to ranged so its quite easy to use 2 LEV tanks instead of a LEV destroyer.
Setup time needs to be removed for sure, but what kind of perk should replace the -1 setup times?
