To add to this, they could restructure the skills needed for the BLU quests, so you are getting your essentials first. Also space the quest skills better and maybe add them every few levels instead of 10.
They could add Eruption as level 20 quest skill, since there's no reason not to get that asap. Also it's flat 300 potency AoE with no fall off, unlike many of BLUs skills.
Bristle for level 25 quest. Plaincracker for level 30, Bad Breath for level 35 quest. Instead of 1000 Needles they could definitely could make Ram's Voice + Dragon's Voice a requirement for the level 40 quest.
I am not sure how they would need to go for level 50 stuff, since there's a lot of really usefull stuff, maybe they could direct you better and indeed adds some totems.
There could be some more tutorials, like explaining why Bristle + Song of Torment is the right thing to do.
