one weapon is a raid-wide drop

Why are you complaining (rhetorical)? It's just like Magmaw for casters, but now melee (apparently). You have the possibility to get BOTH 378 weapons in one lockout period since one weapon is a raid-wide drop. You'll be getting options now. You're getting more love.

One of my very few upgrades wow gold for this content comes off Cho'gall and/or Sinestra. I have to kill two "end" bosses which are considered to be among the hardest to successfully down. And that's just for a pair of boots.

Know you've read that, asking for more when the development has taken initiative to improve loot and loot tables in favor of your itemization isn't exactly a "Thank you." You can't hit the jackpot every patch, sometimes playing the game is more fun than rolling 90+ on your drop.
