Using various WoG scripts is a feature which shouldn't be abandoned in future, but currently we orient on standard gameplay.
Later I'd still like to see major scripts as downloadable official minimods which are used via Era Mod Manager and don't go with official installer (or they do, but they should be for example chosen manually from the available list so the casual users will have less chances to pick undesired options occasionally). This is due to the reason that many WoG scripts are pretty raw and cause unpredictable bugs.
Graphic-wise, the Commanders currently have two possible options.
One is the unique creature design which is used for a some kind of "supreme creature". For example, the Knight actually could have something like an Angel (yes, although I highly oppose such contemporary-religious concepts for Heroes 2). I even had a draft of it based on gk1981
's development inspired by a Bracadian Angel:
The second design solution looks more nice to me for a variety of reasons. It utilises previously unused Heroes 2 Captain concepts:
Gameplay-wise, we must admit that WoG Commanders is a pretty unbalanced thing and if added, the whole Commander concept must be considerably reworked.
