That’s actually the point: let good players from other servers fight each other, but let them start at the same level to keep it fair of course. Else people like Latte or PolarStar only need to make a character there to get the number 1 spot every 3 months…
I also don’t think you should go for reincarnations etc on the seasonal one (except if you want to go really hardcore). Just get a level 60ish with good pvp skills (takes 2-3 days)
I would go for faster progression and harsher death penalties on the seasonal server, but well…
