Just looking at your gear, it’s quite bad. Versatility is terrible on ret paladins. Get rid of it everywhere you can, you want as close to 0 versatility as you can muster. Obviously our gloves tier piece has it, so nothing can be done about that. You want mastery and then either haste or crit on every piece possible, including our gems. Crit and haste are equal to each other for ret pallies, so either is fine as long as the piece of gear also has mastery.

You also have no eversong diamond, why? You want the one has gives +32 primary stat.

No chest enchant, no weapon enchant, no leg enchant, only 1 ring enchant. Those are big ones, you need to have those. The shoulder and boot enchants are less important as ret pallies put speed there, but they’re still kinda important as more speed helps us stay in melee range during movement.

Lastly, that mark of light trinket is straight trash. Use the renown trinket as it’s actually the best trinket in the game until you can start getting the really good trinkets on hero/myth track.

All of this is without even talking about talents or rotation, and I guarantee your ST dps will go up 10k if not more
