on top of that you're a blm yourself and even admitted to losing to the same comps

Yes, I lose many a battle solo queue against 3 man premades- blm or no blm. I also do not like facing a 2 smn group but you do not hear me QQing about summoners or 3 man premades. Do you know why? I have an option of queing solo or making a premade and guess what, I have the option of adding a smn, blm or whm to that party just like you.
Why do you think people will target a Blm over a BRD/MNK/DRG/PLD/WAR/SMN ? Because the BLM HAS AOE SLEEP.

Do you think I am debating whether sleep is a good pvp CC? Of course we are targeted for our CC, we are also targeted first because we are MUCH easier and quicker to kill than a healer- one good reason for my squishy class to HAVE sleep.
