I think I finally know what caused me not to enjoy retail. It’s damage breakdown. In retail you tickle outside CDs and your damage feels kinda meaningless on many specs. You do it because there is nothing else to do kinda but at the end only these 10-15 sec on CDs are the real kill windows that matter. On Wrath every button feels meanigful. In BGs you kill a lot but you also die a lot. No debuff for FC in bg or dampen is needed because people just die to sustain damage. CDs are also not even nearly as powerful as on retail. Literally due to amount of spells added in all these past expansions baseline spells have to tickle otherwise everyone would die in 0,1 sec. In some cases it happens already.
Unless this changes PvP will be in this weird current spot. Other thing that makes PvP frustrating is the amount of mobility and micro CC. Because of it casters cannot really hardcast unless they have as much CC as Demo Locks. Otherwise they get shutdown completely and get absolutely outpressured by meeles who have way more uptime than back in old days.
