I have mixed feelings about the chapters too.
Venthyr and Necrolords were definitely the most interesting ones to me; cool to work with the other covenant and with a consistent story.
On the other hand those two story lines where also the “laziest” ones, since they were more or less the same for both covenants (Necrolord a little more, since they shared the first chapters with the Kyrian); but at least with the little extras “Kael’thas” for Venthyr and “collect the primus’ equip” for Necro.
Bastion would be next. Started off well, with the collectiing of the enhancements from the other covenants… but the Maw & Uther & Lysonia part was simply too rushed. Uther’s change of mind came too fast and to simply blame everything on Devos manipulating him to think of vengeance as justice is quite weak. Wasn’t he the one who convinced Devos that something is wrong and the reason she started to ask questions? Why would she be the reason for his behaviour?
Ardenweald… well, the chapters themselves were okay, but I seriously missed a common thread through the whole campaign; jumping from Tyrande to Bwonsamdi to the Drust and repeat. Especially the Tyrande chapters have to feel strange from Horde perspective, as did the Bwonsamdi ones from Alliance perspective… and the Drust, so many questions. I still don’t understand why they are even in Ardenweald and why they are so powerful, that they can easily corrupt the fae… but on the other hand their leader get’s crushed easily in the last chapter.
All three (Necro, Kyrian, Night Fae) additionally have the same problem in my eyes; they quickly kill off characters we only just started to know and who had a lot of potential: Kel’Thuzad, Lysonia, Ara’lon… although - as pointed out - at least Kel isn’t completely gone yet.
But seriously, my poor little rogue feels horrible now after accidentially killing Ara’lon… and the event only gets one short comment by Moonberry. :_(
