I really like the Mobilisation Effort weeklies, they're usually fun to do, and though they're sometimes a bit heavy on the requirements (the 'do the Drizzlewood meta' every day comes to mind) they are generally pretty fun and refreshing.
I'm really disappointed with the lack of items for some factions though, Olmahkan was bad if you hadn't gotten the latest masteries yet (because you couldn't buy any of the stuff) but the Skritts just straight up only offer 1 skin? Was there really no skin set or items you could add here that you didn't have to specifically make for this (like you did with the Exalted for example)? It just feels so sad to earn Marks that you can then not really turn into anything at all. And even if it isn't (new) skins, you could just make a selection of other items available right?
