I only hope the will not use admob mediation for other ad networks. I mean a lot of people get banned from admob (i wont get into reasons why) and they switch to other ad networks. If scirra will support only admob plugin(like they did in construct2) this will be very bad for game developers. That means , if developers cant use admob, they cant use any other ad network which would mean that contruct 3 will be pointless to use also.
So please scirra, support more ad networks with native plugins, and NOT through admob mediation.
UPDATE : i just saw thet scirra will allow 3rd party plugins. This is a good feature :
