Starting out please help :D

So I am starting out on this server Lordaeron. I have come from cataclysm mists of pandaria and WoD. I really love the paladin class especially Retribution. I saw a thread earlier that said there were alot of ret paladins on this server (completely understandable as they are very good this expansion) but he also mentioned how he wished he rerolled cause he couldn't get in to raids and guilds cause of the big amount of paladins on this server. Please answer me quickly and if it is hard and i should reroll please give me advice on an easy good fun dps with similarities to paladin i dont know. Thanks. This is his thread http://forum.warmane.com/showthread.php?325407-palas-in

Forgot to mention i am planning on PVE but i may pvp sometimes

Dude go for Pala, theres always place for good rets in raids n ****, dont reroll if u like ret, rets are strong af in wotlk
