Hello dear blizzard,
i have idea for terrans players. if you doing wall for terran it is important where you start if you start in top-right you do fully wall (suply,baracks,suply) and you can do on it techlab or reactor. But if you are bot-left side you cant do tech lab without lift up baracks. what will do build tech lab on both sides? thats sometimes bad against zerg who run to base after lift… 
(i apologize for my english)
I have one idea for Coop missions that I think it may benefit us all.
Allow us to use skins in coop,
for instance I would spend money for a few skins if I could use them in coop missions as example I would definitely buy and change Raynor BC skin and many mores. I don’t think it would be hard for you guys to add that future, and I’m sure other people would spend some money as well on that.
Cheers
