Ive been playing Riki with a dual purpose. Its fun playing with invisible guys to start. But ive also noticed we struggle at times with invisible guys. Having us go against invisible guys more will help with wards and dust and all that.
I feel like we've gotten a lot better in terms of dealing with invis heroes. Right now it looks like our problems are winning lanes in the early game. Like last hitting and denying but that could also be from having bad matchups so its hard to tell.
