Everyone know that SCU gonna be nerf in the next patch. But i would like to know to what end you would like SCU to be use for.
At the moment there is 2 different way for them to be.
1st : nerf scu (since they are OP), make them still good unit as a fighter with high micro. ie make a spam scu rambo viable to fight T3/exp (depending of the SCU (cybran scu is weak against exp, but strong against T3 atm) and the player's micro skill).
Going for only scu spam won't be the best solution, but would still work.
2nd : nerf scu, and make them real SUPPORT unit. Even with the best micro, you won't be able to win against percy mass efficiently with a spam scu. making it not viable. But scu would be use as support unit able to make T3 spam/exp more deadly. For example, cybran scu would do low damage, but would still have emp. Brick would be the unit doing the damage, while cybran scu would lower opponent dps, and f*** up opponent micro.
For example, we would see shield UEF scu combo with percival more often.
Of course, scu would still be able to building on battlefront, and reclaim. (which is the goal of a support unit too)
