Alright I've played the first 3 chapters and believe it is definitely a good campaign, it reminds me a lot of Armies of Exigo the way it plays out, and LotR (the music and hobgoblins).
In terms of what I liked, I liked the custom abilities and techtrees, and the faction switch from bandits to "cultists", and I always LOVE custom models so well done, your terraining is very good too and the custom assets used in sculpting the environment work very well- You're way better than I am at terrain.
Feedback:
**The regeneration on the hobgoblins is wild imo, I would nerf it a bit, as its quite tedious to kill them. For the 3rd mission, I think the amount of firemages that are spawned/trained (for me it was at the half way mark after losing the demi-hero) was insane, there was like 25 of them!!
**Consistency in abilities/tooltips is the main thing, which is annoying since WC3 campaign object editor section does not technically work, so you have to update each map one by one (depending on the version of WC3 that is). But some abilities share hotkeys, or have inconsistent style/writing errors. For example I think melee weapon upgrade says it upgrades damage for footmen, knights etc. and has been forgotten to be changed.
