I think would be good idea to introduce "race change" coz lots of people always crying that oh which one is better Yul archer elf or d.elf or what ever. So maybe after they decided that they want to change and if you are 95+ its not so interesting to lvl up again new char so to change race I think would be pretty interesting.
It not suppose to change to different class like archer to nuker but just like if u are archer than to archer but different race. well...
