you beat heroic in a bo1. Heroic doesnt give a flying fuck about IEM (besides cologne), no tier 1 teams does, its literally a live training ground. And for a team like godsent they play like its the major, cause its their opportunity to prove themselves.
Beating #5 in a bo1 when they dont care makes you tier 1. stay delusional mate. No tier 1 teams care about IEM
