The Sett Health regen nerfs
So in 10.3, Sett is getting his health regen nerfed from 9.25 to 8 HP5
A warranted nerf, as atm Sett can even take bad trades and win because he has the third highest health regen and has a passive that makes it stronger when he goes in to trade.
Yet in your 10.4 PBE patch, Sett health regen has been buffed back to 9.25. 10.3 isnt even live yet, you have 0 data collected on how this nerf has effected him, you have sent the nerf to live, but you immediately want to revert it?? Either send it or dont. Is this what 200+ years of experience looks like?
