And what benefits are those, pray tell?
Before you say 'easier handling of mechanics', there are only two ranged baitable mechanics this raid tier (E1S first orbs and Black Smokers at E3S, the latter of which can actually be skipped entirely if the party has high enough DPS), and the tier in general is ridiculously catered to melee. For the few mechanics that may be tricky for melee to handle, teams have come up with ways to get around that (like having everyone stack on DPS flare in E2S, and orb configurations in E1S that let the melee stay inside for uptime). For the few mechanics that force melee to disengage from the boss, you don't lose any more than a single gcd at the very most unless the boss is positioned poorly, you have ping too high to risk getting hit, or you're just bad.
Then again, I'm not sure why someone who doesn't raid is trying to drive-by snip at an OP who has done their research.
