I'm going to compile a list here of things that I want to make, others have asked me to make and what I won't be making.

thefinalstrife3 asked for a generic lord type:
Working on it, it will probably be done in April.

Kami asked for a generic lord or hero, anti-large units and a wardancer unit:
I now have 2 new generic hero types, so that request is done :)
Generic lords are done too.
Working on a low and a high tier anti-large unit.
Wardancers might come at a later date.

Metal Marty asked for a mount for Alith Anar:
This might cause a few issues, like how his Decoy ability will work. Since that's one of his signature things, I don't think I'll do it.

XIX Victorious Aut Mortis asked for a hero, named something like a herald to the shadow king:
The Herald of the Shadow King is done, have fun with it!

thefinalstrife3 wanted wolves:
This could be used as an army ability, like how the High Elf Gates can summon Eagles for a short period of time. Interesting idea, but I'm not currently working on it.

Caesar suggested a shadow dragon:
Not going to happen. The Shadow Phoenix isn't that lorefriendly already and I don't see a creature that's already very rare to have an even rarer variant.

Argon would like a Nagarythe version of the Ellyrian Reaver:
Raven Herald Archers fill this role, but they're an elite unit instead. I'd say this request is done too.

Current to do list:
Alatar, Prince of Shadows. A legendary lord for Nagarythe who focuses on Nagarythe and Coraith troops.
Calaidan, Archmage and heir of House Coraith. Another legendary lord, focusing on construction bonuses and magic.
Update Griffon mounts to the High Elf version.
Retexture the Raven Heralds.
Army abilities and campaign mechanics, like Eltharion has.
