With how badly they dismantled EDG, you have to wonder if their loss to SEN was just a minor choke considering Less wasn't in form + Saadhak went -28 which is bigger than every +/- deficit in that lobby combined. LOUD also beat SEN 2-0 in their first match as well, and their loss to GENG despite being in form only shows the strength of APAC's 1st seed.
There's a very strong chance that SEN won't even be reaching the finals in all honesty, they're somewhat in the same level as PRX, so there's pretty much a gap between the top and bottom 2 for the playoffs. I think SEN just happened to take the easiest road (EMEA) and people are failing to see that.
