seriously it seems like some people just like their opponent to have no commander at all.
On the contrary. If you have seen me play with Stormless you might know that I enjoy all commanders, meta or not, and I love well played abilities and good use. Maybe it's my latency and performance issues in 4v4 that I seem to lack the ability to avoid this strike reliably even when spotted. But that doesn't mean it doesn't need adjustment. As you said a well played CAS doctrine can destroy and army.
Of one player at his base. And you can see the scout plane coming.
Tactical support cripples an entire area with a very good chance of stopping more than one player in their tracks.
Tactical Support incapacitates armor and nullifies it's infantry support with lack of proper counterplay. It rarely matters if you move or not, it will hit you. I play a lot of 4v4 AT and this ability promotes bad game experiences and click and win situations.
The only reason I think we don't see more complaints about it is that people haven't caught on on it's potency and lack coordination in random games. It's only saving grace is that it is very expensive.
I'd much rather see it toned down, give it a cost reduction, and then it might be a commander we see in 1v1s with reliability and inventive use instead of hoping for that one expensive ability to win me the game. Wouldn't you agree?
