Problem is not just commorph. Problem is when players morphing their coms and loosing game because they just want get award "Master and commander". Not help team win. I's not team, its my game.. One skuttle/cloaked roaches/some bombers/infiltrator and com ir lost. And resources + time also. Trollcoms rarely make cost.. And all team is doomed.
Many games is lost because players just morph their coms and sen them to front to be destroyed. I's annoying as some genius start build 'shiny singular' at start in small maps.. And there is some players who immediately resign after com is lost.. Ok one time, but not three, four games in streak and all three, four games is lost.. And also there is genius who try reviwe his 'lost honor' and start building athenas. :D
And problems start when nabs are watching this and starting doing like that..
Only few players use commorph effectively.
I think there is no 'cure' for this. :D
