This might be a tad off base from the topic, as its mostly talking about mechanical ideas/issues around Vox, but I feel like out of everything a Vox has, its not their buffs/maluses that are the core part of Vox its the culture/lore/accents that they use for the most part. It might be me not giving a single flying hell about actual species traits (which is likely a minority), but the Lore and RP aspects of a race along with the general community that species has on the Station are 1000% the focus that a player should be having when deciding to play it or not.
SS13 is an RP game with a focus on community, its not an MMORPG that requires you to pick the most OPTIMAL character to dunk on antags/dunk on sec/go tide with less issues. Sure the bonuses might make you more "unique" but a few traits dont mean jack if you arent putting the effort in to immerse yourself in the Lore or Culture of a species.
