I have never in my entire life felt that any of the reputation rewards ANY faction in the entire game offers you is worth the Grind at all, they are simply, all crap!
What is the point of Grinding Therazane for example? Yeah, I get the expansion is old, but she doesen't sell recepies or anything, she sell a tabard and some outdated enchanments. Not recepies, direct one use enchantments that aren't useful for anything. They may have been Useful back in cata, but even then, you could get MUCH better Enchants.
Another example is the Golden lotus. Two weeks doing constant dailies for Crap rewards. They literally sell patterns that are worse than LFR gear. What the hell is even the point?
Don't even get me started on the Garbage rep rewards for WoD either. Some stupid potions you can only use in zones you're never in, and some stupid mounts and pets
"But Bamyouhaveaids, some people farm Reputation rewards for mounts and pets." Grinding for some stupid mounts and pets that I have enough of from before, doesen't really make it justified to make all these cool factions if their rewards are shit! I love Therazane, but doing quests for her is so boring because I know that I'll get nothing in return, even in Cataclysm, you really got nothing in return aside from a couple of mounts.
Can blizzard please make it so Reputation rewards doesent suck? What about making Rep rewards an alternate way for filthy casuals like me to gain good gear without commiting to a Raid? They take weeks upon weeks of Daily quests to complete, and we get nothing back for it. Giving use some useful things like POWERFUL Consumables, Armor and some Cool Mounts and transmogs.
