I think they type of rep grind is very very slow and could use a small boost? Mby just the weekly quest in dragon isle gives small rep boost to all small factions in the dragon isles aswell would be a great idea, even if its only 500. Would love to hear others opinion 
Donât forget to fill in the talent tree for them at the NPC as you progress. I didnât even realise it existed and was half way through before i discovered it, but that helps speed things up a little.
Also picking up and stacking the buffs as you go along will really speed things up as with the right buffs you can take on multiple packs with ease and just aoe everything down.
