Def not a new player this early, at least play out till after Last Chance qualifiers when a lot of teams are making moves, you have Sinatraa coming back, etc. Just practice as stupid as that sounds. I don't mean like signing up for smaller tournaments (though that doesn't hurt). I mean like finding out what version of the current roster works best with what agents, then make strats off that.
I would imagine C9 knows more about what they need to do than we do, but that's just my opinion. Also when I say Sinatraa coming back I don't mean C9 should pick him (though if you can handle his baggage I think he would help literally any team in NA, even as a 6th rotation player on SEN) I just mean that a big name might show up because teams are making moves for big names like Sinatraa after Last Chance Qualifiers. As the teams are set for Champions at that time. Hey C9B might be in Champions, this is just assuming they don't make it.
