To each their own, but I think removing the differing life spans makes the races more flat and indistinct.
Personally I think they're twice as flat and indistinct when they all live to be 450 years at minimum. From Half-elves to Dwarves to fucking fish people, everything seems to live ten times as long as humans do in fantasy. I agree differing lifespans is interesting, but humans shouldn't be dying at less than a quarter of the lifespan of everything else.
My biggest problem is that searches don't fucking work anymore. It now defaults to searching the channel you're in, but what if I'm look for a particular message and I don't know what channel it's in? Then there's also searching PMs is so much more complicated now and doesn't even show you who sent the message in the results.
