OP posted this on the EU paladins forums

with the title being "Retribution Paladins are Fine! Thank you Blizzard!"
Let me clear some things for you OP:
A class isn't balanced over you flying, landing on players with PvE gear hardly attacking back trying to avoid you and running away mean the class is fine.
as you mentioned in your post "But I admit I am not good arena player" the reason you don't see the issues we usually face, which is in arena/RBG at higher rating..
So do most of us a favor, create an arena team (3s or 5s) and record every game you play, have recount on and monitor your DPS/healing vs DPS/healing the classes you are teamed with and against. how it is possible for some classes to burst you so quick, you will either be stuck in a stun/fear/deepfreeze wonder what the hell just happened.
Do that, go through what we went/still going through, then get back to us.
Thank you
