Class mechanics are the problem. If you are a good rogue, you can get a high arena rating naked.
Damage is so broken that its just about broken classes. The best class have damage immunity like pal does.
The second the damage reduction causes me to be able to play. The next thing you find is dps has more healing than you and can prevent you from healing at all. This is while most of the time dps healing is not interruptable for holy priests.
Fear has a long CD and stun requires casting dps spells to reset. Meanwhile we are being stunned, chain feared, interupted, out healed and hit with massive dps.
One player out geared me. Totally destoryed me, spit on me and put the thumbs down flag. Nothing I could do. Another would just out heal damage as dps, see locks. Rogues can just stun lock you and kill you. Nothing you can do. Trinket a rogue will withdraw and repeat. Blizzard designed the dps so they would be able to kill holy priests. Made dps damage so high the low skill mythic raids can one shot.
These players think they are great and balancing then will make them see they are garbage skill wise. Its never going to happen, they will never make holy priests balanced with other classes. They will just over nerf holy as needed to make sure.
BFA you could be unkillable to dps because they were brain dead. Warsong I could take the flag and return to base. All the other team attacking me. Basically because they could only do their raid dps rotation. This is the HC and mythic raiders. Most normal and LFG raiders cant do high dps in good gear.
Real decent players and they stun and dps me down. I cast nothing.
Basically WoW is designed to make high gear players feel skilled. If the mythic raider goes to PvP he owns with OP damage. If he goes to mythic+ he owns with high damage.
Its so bad in mythic+ they get healer carried. High dps but no cc, interupting or avoiding damage. Healer just has to out heal it all.
Tanks over pull and chain pull with the healer oom the whole way. No concept of pace. Oom mana because dps dont do anything other than their raidering dps rotation. Yet they are skilled, with 215-220 gear. Perform like +9 is imposible. xx deaths later.
Dont get me wrong but some players are geared and do have skill.
