No problem.
Actually, it's 2500 for each submission. Just post feedback for four maps, you'll get 10k.
Thank you so much man! Too bad it says the event only runs from September 28th to October 1st, and I made this post on 3rd
Anyway, I've picked 4 maps from the lot, played the crap out of them and submitted some feedbacks
They are all amazing maps, will definitely try out some more when I have time tomorrow
I hope I can still get supply rewards... If not then eeh it's okay perhaps next time, hopefully the map makers will find the feedback useful at least.
