They really didn't the score line on map 5 may be close but SEN was clearly worse than G2. They also had alot of close games against other teams like MIBR so i wouldn't say they were really very good.
IMO the gap in bangkok was HUGE. For me i had in mind top 3 would be G2, VIT and T1 but apparently VIT just stopped using their hands and eyes in the playoffs and got rolled. EDG was of course 4th but I put T1 over them over bc i like T1 more. Than it would have been DRX and TL who were kind of mid. Followed by the poop of the tournament which were SEN and TE
