Of course I'm being a little to literal here, but I've never been able to take raiding seriously lore wise, a puny mortal warrior can survive a hit from something 5000x the size of him just because he's specced prot?
It wouldn't be much fun if we had to wait outside until she turns up wearing Garrosh's shoulderpads and axe.
Lor'Themar could easily kill Jaina 1v1 , way more powerful character. So the argument should be why doesn't he solo it?
Lore and stuffs I suppose
Thrall solo'd Deathwing. He'd crush that whore.
Its the same reason why the US govt didn't nuke Afghanistan to kill a few people.
Because having Dalaran there would take away from the heroic feel of the raid.
It should have boiled down to Jaina vs Garrosh. Maybe they're saving Jaina for something else just like how they're saving Magatha Grimtotem by sweeping them under a rug and forgetting about them.
