genie is already out of the bottle. limiting what people have only contributes to FOMO and people playing the so-called "forever-chars" instead of rolling them, esp. when you consider that some people have never, in all their years, gotten a greater or even a major. the award CD has only inflamed that feeling, too.
hearing the phrase "rotation" makes me think i should spend my current awards NOW rather than think a character through. this exact same thing happened when the giants got removed.
the real issue with the fantastical races is that they are, for lack of a more appropriate phrase, not "moderated" properly - inversely on the major-award side of things, some of them are so coveted that players who use those awards feel incentive to play "carefully" so as to keep their character in a playable state. fey'ri/vampires are a good example of this. (once you're outed you might as well call it quits.)
the team shouldn't worry about changing the scope of available award races until they decide how exactly they want these things to be integrated in the server in a way that doesn't (inevitably) get boiled down to race+ syndrome. (genasi, tieflings, etc.) they need to feel like their own "thing" before the racial bonuses figure into things. instilling culture in a race/area of any RP server is incredibly difficult, but if it can't be done, there's no point in having awards.
award races must be discrete beyond the stats they give.
time and time again, if you saw an earth genasi human, that's a weaponmaster. if you saw an air genasi elf? that's an arcane archer, probably shevarashi. earth genasi h-orc? that's a ranger weaponmaster. the stats pigeonhole the builds/characters, and the awards are frustrating to get, so people want to get the most "juice for their squeeze" instead of focusing on the character itself. that isn't a "bad" roleplayer problem, either.
and yeah, i realize it's incredibly difficult to moderate all the unique creatures running around when you've got a playerbase of 200ish people and maybe 20 staff on a good day, but changing what's available won't fix that. it doesn't matter if avariel and fey'ri are replaced with githzerai and githyanki if, say, the gith don't come in swinging hard as "WE ARE GITH. WE ARE DISTINCT FROM OTHER THINGS. FORGET MY +2 WILL, IM ALIEN."
