Your either trolling super hard or just absolutely clueless sry :/Rets are Blizzard's favourite child. Following vanilla and ever since (2006), they have been the most OP spec in the history of the game with the possible exception of WOTLK DK's. In fact, Rets qualify as one of the most OP specs in the history of MMORG's in general. Key abilities include:
-The longest stun in the World of Warcraft ever.
-Immunity to being kited.
-Bubble that make one completely immune to damage while still being able to attack.
-Abilities such as Lay On Hands that instantly restore one's health to 100%.
-Infinite Mana.
-Ability to use hearthstone (RECALL) while being bubbled.
-Excellent heals while dishing out excellent DPS with no penalty on their DPS.
-Excellent DPS cooldowns completely unsuited for a DPS/Healing hybrid such as Ret.
-Immunity to being griefed or ganked while out in the world questing. If you go one-to-one with a Ret you will lose, if you go two versus one against a Ret you will still lose, and if you try to go three to one against a Ret they will just bubble and hearthstone.
-Excellent in soloing Raid content.
-Fastest mount speed in the World of Warcraft.
Recent bonus abilities:
-Pet
-DOTS
-Snare
-An ability similar to Rogue ability Sprint
-Ranged execute
-Several Ranged DPS abilities
------------------------------------->With all the above in mind, it is not hard to see why there are more Rets than Rogues.
