People cried that they wanted Mounts, Titles and Pets account wide, Blizzard made it account wide.
People cried that reputation grinds on alts were boring, Blizzard made it "semi-account wide".
"Leveling is hard, please make my alt level 90 with at least 460 ilevel."?
"Profession leveling is expensive, please make my alts profession level 600."?
"Gear is hard to get, please give my alt full epic gear."?
"PvP is boring, please make my alts Honor capped at a press of a button."?
If you don't want item X or Y on your alts, it's simple...
DON'T do the achievement that awards said item.
DON'T farm said item.
Stop crying, and stop "asking" for more account-wide crap, what we've got is more than enough, and was not really needed.
Next thing we know, they're selling Boost packs at battle.net store... Sigh.
