There are handfuls of teams in the 2-2.5k bracket running this comp. It is ESPECIALLY good against RMP, in fact I would say its a perfect counter, my 3v3 team rarely looses to RMP. RLS is harder but very beatable in this comp. I can't think of the name of the team, or what tournament it was, but last season a team won an MLG tournament running this comp, beating out several RMP/RLS comps
