Cop and Jacky are now on Curse's alternate Team, LoLPro. EDward hasn't said what he's going to do. He may go back to Europe, or might stay in NA (but I'm not sure many teams are looking for supports right now - maybe CLG, but I doubt that).
IWD is a suprise to me with curse being a big organisation that just "Hired" someone who was banned as well as Pobelter purely because of his age....
IWD wasn't just "hired". He was on Curse Academy the entire time he was banned from the LCS (both as a player and a coach); Saint himself mentioned that he would probably go into a coaching position for Curse and have IWD replace him for a split. After watching a few of their games on Voyboy's stream, he doesn't seem toxic at all. To top it off, he's a great jungler.
Pretty much the same goes for Pobelter; he wasn't picked up purely because of his age. He's a phenomenal player, and was already being looked at by Curse (and many other teams) loooooooooooooooooong before he turned 17. The only reason he wasn't in the LCS last split(s) is because he was too young (you have to be 17 to play).
Either way, both IWD and Pobelter are strong pickups in my opinion.
The only change I'm not sure of is Aphromoo for Cop. Aphromoo isn't bad, don't get me wrong, but I don't see how Curse gains anything from swapping the two. Maybe it's a communication issue, maybe he wanted to play with Jacky, who knows.
