I’ve tried to find out if spell resistance works correctly in PvP on classic servers, but information was very limited, sometimes controversial…
I’ve tested shadow resistance (220) against warlocks, shadow priests.
Dots: application resistance - resist doesn’t work. Dot ticks - resist doesn’t work (not even partial resistance).
Direct spells - partial resist works.
Crowd control - full resists.
Not sure if it should work like that… Do you guys any valid information source how it should work on 1.12 wow servers and a data of how it actually works here - on 1.13 classic servers.
