well lets look at stats for one minute..
Device is the highest rated player in major with a stunning 1.28 rating. In big events he has 1.22.
Elige has 1.21 in big events and 1.16 in majors
ZywoO has 1.27 in big events and 1.17 in majors
s1mple has 1.29 in big events and 1.24 in big events.
If we look at those stats it easy to see that s1mple has the best stats with Device coming close as second. ZywoO is not far behind. Elige is 4th in stats, but as the only main riffler (atleast in the past 9 months) I think hes stats is a bit misleading.
I think the top 3 is Device, s1mple and ZywoO in that order, atleast for now. Astralis won both majors and I think that will play a role. I still think anyone of those 4 could grab it.
