TLDR:
Duelist: Havoc/Dgzin/Sato
Flex (Gekko, Kayo, Breach, second duelist or senti): Askia
Info Initiator: NZR
Smokes: Pancada
Senti/IGL: Zap
It's already chalked, gotta look ahead. Only piece worth keeping is NZR but they are in desperate need of a non-recycled IGL and star power. Kon4n is legit awful, Mwzera is the worst duelist in Americas, Havoc doesn't know how to play any role he's on, and Khalil is just washed. Here's what I'd do:
Keep NZR as your main initiator
Get 2G's Zap as your IGL (has won 13 of his last 17 games IGLing in T2)
Get Pancada
Give Havoc a chance to compete for the duelist spot with dgzin or one of those tier 2 monsters, Sato being the most notable
Askia to add flexibility alongside the fragging
Not recycling the same washed T1.5 players, we get up and comers as well as adding the only 2 main BR scene guys that are good and available.
