This year?
OS does seem to be leaning on Twitch more and more as a promotional platform in order to create "events." But they're hardly the only ones doing this.
I can only
imagine the rage this announcement will invoke in some people waiting for the OSFM rosters--knowing that the rosters are actually done, yet they have to wait another hour. Some folks are going to
lose it.
EDIT: Case in point, this thread already has all 4 of the ratings as 1-star ratings.
