I mained a rogue in Mythic Tomb, for anyone who cleared mythic tomb will understand why rogues were god mode for clearly the raid, especially avatar and KJ. After tomb rogues were basically obsolete when they made cloak not as OP and feint. My guild had no Boomies so I also made the switch when asked, this is the dumbest decision you can do, making a class your main YOU didn't pick, I was miserable, it wasn't fun and boomkin was in a good spot in ANT, they weren't top on ST but they were pretty up there on all AOE encounters, and still I just wasn't having fun, to the point I quit when we were on phase 4 argus. Just wasn't worth it.
Take my advice dude, tell em to fuck off and play what you want, or at least play a range you want to play. I'm playing Mage and Hunter atm and sticking with my range atmosphere this expansion to see what it's like as I played rogue since Vanilla.
But to stick to the topic, melee have never been fav, we saw this hardcore around the time cata hit, someone could link the old paragon video of their Al'akir fight, that's when it started, and Council in BoT. prior to cata, melee weren't in heavy demand(Hell in vanilla raids were half Rogues and Warriors) Even TBC with the OP warlock SL build you'd still see heavy line ups of warriors and rogues even the odd feral,ench. but fights weren't anal anti melee until that era of cata where guilds were like "Shit....we can't bring this many" Yes maybe 1 fight was fuck off melee, but not half the raid like we have now. Best bet, stick ranged and start enjoying it.
