Mages have an advantage on newer servers as it's cheaper to ml train with exercise wands/rods.
If you have a high skill ek/rp. You will be alot a lot slower until like 80 for ek if you decide on sea serpents. And like 90 for rp if you decide on grims.
After 150 RP can match same xp as mages. Ek gets close at 200. When you can get around 3kk/h in asuras or barkless elves.
At 250 mages autowin auto win with Falcons.
That said . Rps easiest to solo / farm bosses.
