I found EW decent but not spectacular, overall. It really needed to be two expansions as originally envisioned in order to the have time and space to develop the ideas they were going for, though. You can tell they were running out of ideas with Garlemald in particular and just wanted to get past it. Jamming everything together results in a lot of overly compressed storytelling, nothing gets time to breath and develop organically (and the few times it does try to slow down, like meeting the loporrits, become all the more jarring), and the whole thing ends up feeling rushed. It also has the side effect of not giving Estinien much to do; despite his joining the Scions being a big hype point going in, he's taciturn and not particularly scholarly, so when everyone is standing around talking, he's mostly leaning against a wall off to the side somewhere.

And the patch story is pretty clearly a side story padded out to fill in the MSQ while they work on something else, which ironically gives it the opposite problem.
