They have a solid core with penny wippie and their coach, so start around them. First move penny to Jett, I have no clue why they moved him off it. Wippie is flexible enough to play anything at a top level. The IGLing is definitely a problem in some capacity. The only reasonable IGLs available are Shazam, steel, patching dazzle, and vanity if g2 can buy the contract. Honestly go for vanity or dazzle, but if you can't keep Shazam. Dapr is fine too on Sentinel. The only issue is he is usually antistrated pretty hard, so they'd need to spend some time fixing that. Ideally, I'd pick up smoke. Smoke is an insane Sentinel. Lastly I'd pick up shot_up for flash initiator. That guy is still playing insane
