I see zero issue with gender-swapping certs, not even lorewise. Our clones are sculpted from human cadavers, among other things - they're not just grown in vats. For a society that is capable of these things, I have serious doubts that the ability to make a clone of someone that is effectively them, just with a swapped chromosome, is exceedingly difficult. Obviously some funky genetic engineering and biology work would be necessary to make it viable - you can't just go swapping an X and a Y chromosome blindly - but I really don't see that as being outside the realm of possibility, either technologically or economically, for capsuleers at least. Speaking in terms of game mechanics though, gender in EVE as far as our characters go matters in like, three places that I can think of: sculpting meshes, available/usable clothing, and for roleplayers. I'm not even really sure that this should require a certificate/purchase, but then again I don't really see the point in swapping back and forth every other day so maybe that's just me.
Race changes I am very, very iffy on. Again, much like gender, this is something that after a certain amount of time has little to zero relevance to anything except sculpting meshes, available default clothing items and hair styles, and roleplayers. Because it seems less of a super-personal attribute, I personally don't see the point to having these yet, but if CCP ever got around to adding the race-blending features to the character creator that were talked about once upon a time, I would definitely consider supporting it.
I can see a number of possible issues with name-swapping certificates, some potentially major, most minor. I'd be OK with this under certain specific circumstances - like having it attached to a gender-swapping cert to be used during the swap or sometime after. Name changes should largely be kept out otherwise, imo - save the obvious cases of abusive/inappropriate names or the occasional one-off "okay I really fucked up on this" that I feel should have to go through the GMs as is the current policy afaik.
Hats/clothes... obvious yes.
There was also a mention about people complaining that the old pirate log items were no longer in the loot drop tables. Hopefully that means they'll get updated and re-added at some point.
Standings: I don't like standings decay as a concept. I also don't really like removing them as a gateway to higher-level missions - I would prefer to lower the bar instead (current values are 1.0 for L2, 3.0 for L3, 5.0 for L4, fuck knows for L5) and just make it require less work. I want standings to become visible again - as an optional thing. Add a thing to our character sheets that lets us mark factions and corporations to show off our standings for.
