They're okay, but they're not the best. I've voiced my concerns over keeping mimi and petra on the team previously, and when petra left I was excited but that immediately wore off when I found out Nelo was put into her place.
I don't know how old you are, but petra and mimi are a package deal since CS days and G2G kind of fell into the trap of keeping them both with mimi even having her contract extended until 2027 (this needs a fact check but I'm lazy to find the announcement). I very strongly believe there are better IGLs and scan players in the GC scene.
I'm sure the vibes on the team are good, but vibes aren't going to bring you baseline skill. There's been a clear sign Turkiye has good players coming out of it year after year and GC is no different. With the amount of resources G2G has they could just build a turkish GC superteam around amy and vania. I think amy and Safia are two strongest sentis of EMEA so replacing amy isn't a thing they should consider.
