Mortality server. At level 70 with full exp bars, you die and never come back.

Server globally gives exp based on your level, so level one gives 1*(num) and level 50 gives 50*(num)

(Num) can be mitigated with exp pots that are modified to give .75 percent exp instead of multiples of exp. Mobs can cast spells that give 5x exp and that becomes a bad thing, have to get to an NPC that cures it or have it as a dru/shm/clr spell. Some endgame mobs may even do a selfcast 50000exp on players when the mob is at 5 percent health or something. The possibilities are fun to think about.

Killing mobs gives exp like normal, but there would be a lot less random killing of mobs because it takes time off your “life”

Can do trade skills to make food that gives .75 exp instead of 1x, but mobs that drop the mats give exp.

Raid mobs and endgame encounters drop single charge items that take away thousands of exp points. Can make it interesting by making the spell targetable.

Getting married using a marriage NPC (maybe an in-depth quest) makes the married characters gain .90 exp permanent modifier, extending their life

Top end gear has negative exp clicky on BP with one hour cooldown. Self-only cast. You could even have weapon procs that take away exp.

You could keep the necro sacrifice in place, but mitigate the spell by hugely nurfing it somehow. Make it so it only works on level 70 players and put an 8 hour cooldown on it or something. But make it so a successful cast gives 50k exp.

Not sure how the server would “kill” you off at 70 with max exp, but it would have to do it by archiving your account somehow. Maybe just booting the character and making it inactive in the DB

These are just the ideas off the top of my head. My hope is someone with the time to implement this takes it and runs with it.
