I personaly, think that whole “elf-a” issue is kind a… overreacted.
Yes, we have that mutation. It could have in-game explanation (scientist just named his/her genetic creation after mythology creature) or metagame explanation (contributor just wanted to create Tolkien-elf-like creature to have it in game). Either way - we have that mutation. Some people like it, some people hate it, some people doesnt care enough to quarrel about it (as I am). But that attitude might be placed in many aspects of game - drugs, furry stuff, balance issues etc. Like Bonevomit mentioned in "balance… " thread, this game is collective work of many people, who have a lot of different tastes, which might often be controversal. And, unless devs accept strict rules about what might and might not be added to game, we are bound to eternal arguing about content.
I suggest to take things as they come. If someone bothered himself enough to add elf-fairy-sylvan look mutation… well thanks to his/her effort. I might give it a try if I would like to play such a character. If I dont like something - I’ll just dont use it. Yes, devs might be more picky about what they are merging with core game to avoid some silly stuff but… imagine how it would slow down development process if every player suggested item would be discussed by the dev team (with possible arguing and so on). Maybe they will commence some “kill-it-with-fire” purges, when they will finish core issues.
