a bunch of permanently discontent folk that are impossible to please because they all want
Not necessarily permanently, but their anxieties and discontentedness is more complicated, leaving them liable to radical swings in politics. Canonically, I see these people as the urban poor Garrosh sees when he comes to Orgrimmar for the first time who start flocking to him because he's a young and vital leader, and is willing to vigorously prosecute the Horde's interests.
All fine really as examples.
What can Dalaran mages do that our shamans and warlocks can not?
I can do a longer post on relevant magical traditions perhaps, but essentially they're fundamental different traditions which are meant to do different things.
Mages are more specialised whereas Shaman are more versatile. Shaman require fewer reagents or infrastructure, and not necessarily much training and in general are less expensive to maintain, whereas mages can do higher level things.
As particular things, mages can teleport, do portals or construct complex magics constructions or infrastructure. Shaman can't generally do those things but are massively more versatile, they can heal, significantly affect the weather or natural world such as making a river flow different way.
Warlocks are complicated because they're a diverse tradition, but they're generally focused on destructive stuff, so are the most able to damage things.
Can they provide mercenary aid when called upon? Which of our tactical deficiencies can they cover?
They've got a limited number of magical engineers, battlemages and anti-magic forces. Those would be the main capabilities you lack.
For example, they have experience channelling ley lines in a way that other groups just don't know how to do. If you wanted to concentrate the magical power of Alterac somehow, or create magical batteries the arcanists (magical engineers) would attend to that. If you wanted someone to charge into a highly hazardous area against tough defences, Dalaran has battlemages for that who have extensive training and equipment for such things. And then yea they also have anti magic stuff that's relatively unusual, think stuff like Spellbreakers who are able to nullify hostile magics.
They could offer merc forces yes, but if you want the specialist stuff that costs a lot.
Scarlet Crusade directly was said to primarily offer rewards in terms of territory transfers and diplomatic recognition, and direct military equipment and supplies. If that's still true, then maybe instead of industrial aid, what we really want is the territory and a large amount of military equipment and supplies that can be rapidly used to bolster the quality of Grok's warband. That's something the Scarlet Crusade might be able to cheaply afford, and greatly increasing the overall quality of our forces would mean we take far less losses in future engagements.
I note 'primarily' here. Yes Ironforge has industrial capacity, but it is still an influential kingdom. Some of this is a matter of efficiency. It's more efficient to go to Dathrohan for diplo recognition just like it's more efficient to go to Kul Tiras for ships. Howvwer. It's also a matter of inclination as maybe Kul Tiras wouldn't want to provide you with a navy etc.
also what part of lordaron did we help push the scourge out of
All of it, all significant scourge forces are dealt with now. The Scourge would have to make a new landing, and all their bases are gone.
Still lots of wandering undead and maybe some low ranked groups but nothing significant
Say, come to think of it, shouldn't this just be Kargath, not New Kargath? Looking at the wiki, New Kargath is the name of the post-Cataclysm settlement
It should indeed be, shall note for the chapter later
Hmmm maybe they have a fancy trinket to help with mining? It can be used to help in making an underground city.
Just tell the Earth spirits to do it with dark shamanism, is fine. The Kirin Tor are unlikely to have such a thing.
