no one cares about ranks (#1 - - - #30) teams can all beat each other
RNG > MIBR
MIBR should be #7 max
FaZe having 1 good showing in a 'Tier 1' Tournament is not enough to be above NaVi and ENCE. Otherwise the list is pretty okay, also rating MiBR on the same level as NaVi seems a bit biased (yes I know I'm a NaVi fan but at least they have the results to back it up) after losing to them at BLAST as well as their poor showing at Starseries.
Edit: Personally I think ENCE will drop off by July and that MiBR will have a slight resurgence (though they still likely won't be top 3) but right now we can't seriously say either FaZe or MiBR are consistent Top 5 material, especially not MiBR.
