I think the result for DRX v Talon would be determined if DRX had managed to settle the roles in this iteration of the roster, and MaKo somehow gets to IGL more comfortably. (I know what MaKo has recently said about taking the IGL role after stax departure). I think it'll be interesting to watch how they've done a reset in the off-days of Pacific before heading into that match, especially MaKo.
TS and GenG would also be interesting.
The new additions for TS have been showing what they're capable of, which has been a good help and match to invy and jremy's firepower. They also have a week to prepare for their final match for group stage, so if dummy could cook up some antistrats for GenG, then TS has a chance. Though, given they still have tendencies to have a hard time closing out an early lead, I'd still pick GenG to win.
