What about this - stalker shoes get a rework that works like this:

- ability stalk - cooldowns 8 seconds - range 10 meters
- skill puts a curse on the target that lasts for 2 minutes
- skill can be activated within cooldown of 8 seconds while the curse is activate (last for 2 mins)
- upon activation you get teleported to the victim
- the curse breaks if i gets damage from more that one player
- while the curse is activated you have a movement penalty of -10%
- the curse itself cannot be cleansed

Basically it breaks the mobility meta. But is not group gank, as damage from 2 players curse breaks. It is high commit and not bound To a super expensive item, but readily availabe

Remember u still can kite this - warbow frost and already -10% mobility on victim. Victim gets additional 10% from bow passive..u just can't reset endless
