So, I'm going to approach my reccommendations from a systematic point of view.
1) List ALL the ROB mains/people who use ROB AT LEAST 60% of the time/ those who use it less than that whose ROB is unquestionably legit:
Stingers, Holy, Chibo, DullRazor, Waffles, JJVirus, TheMike, Buenob, Dedw8, ZOM~B, HugS, GW, Waffles, Mizu, Ninjalink, JGWentworth?, TinMan, Mister Eric, Mr. E, T0mmy, JamnToast, Silhouette, CJT, NAGACE, and a resurgent Nacker. Those are all I can think of.
2) Realize that Power Rankings are DYNAMIC, which leads to me looking at 10 BLANK spots that need to be filled. Fill those spots based off of tourney results and activity. The list hasn't been updated in like... forever so for my nominations I chose an aribitrary beginning date as of November. I personally think that PRs should be updated every 1-2 months, but due to the large gap in updates I allowed for more data to influence my nominations. Of course, more recent data trumps older data, but consistency is paramount.
Bearing that in mind, adding my own tourney results (Pound+another tourney where the bracket got lost, that I posted the results to here (I think) that didn't get added to main page prolly bc of that) with those who have posted results (or easily findable results via a quick search through regions) since Nov 1st, we get:
Stingers, Holy, Chibo, DullRazor, Waffles, JJVirus, TheMike, TinMan, T0mmy, JamnToast, silhouette, CJT, NAGACE Nacker
3) Toss in a few "wild cards" that we can somewhat safely assume have played as ROB, but didn't post and we have:
Stingers, Holy, Chibo, DullRazor, Waffles, JJVirus, TheMike, TinMan, T0mmy, JamnToast, silhouette, CJT, NAGACE, Nacker, Overswarm, Ninjalink
I'm going to whittle it down not to ten but ten + "wild cards" to allow for the NLs and OSs (and possibly Holy if this MK business is true) of the world. This is no particular order:
Holy (WC?), Chibo, Stingers, DullRazor, JJ, TinMan, TheMike, T0mmy, Silhouette, CJT, Nacker, OS (wc) NL (wc)
If any of those people listed above are inactive (due to some oversight during my breakdown) replace them with someone who is.
My opinion on the "wc" thing, slip them in as a x.1 ranking. like... if we think OS has the 4th best ROB tho he doesn't play as him, put it in the PR as
4th Place ROB
--->4.1 Overswarm
or whatever.
