If you'll excuse my refutation of this...
Exactly two people chose the same RM, out of 16 that had competed in previous compos. Those two are Brandon (who has a weird fascination with Splash Woman ) and Chernabogue (Crash Man). Otherwise:
Hylian Lemon (Hornet wily, Hard 2011)
Willrock (Air wily, Elec 2011, Flash 2010)
halc (Blade wily, Time 2010)
prophetik (Dust wily, Spring 2011)
Sir NutS (Blizzard wily, Heat 2011) (lol that's kinda ironic )
Gario (Magnet wily, Wind 2011)
geoffio (Tomahawk wily, Skull 2011)
Main Finger (Gemini wily, Napalm 2011)
Cyril (Shade wily, Blade 2011, Cold 2010)
Xarnax (Spark wily, Knight 2011)
neblix (Flash wily, Plug 2011, Galaxy 2010)
Rozovian (Crystal wily, Chill 2011)
LuketheX (Skull wily, Slash 2010)
Jakesnke (Grenade wily, Snake 2011)
I'm not counting TGH, even though he's had Bubble Man both times, he didn't pick this year, he just replaced Emunator, who had already picked Bubble Man.
not meant to offend or anything, I just like making lists. :3
