I normaly don´t do this but still gonna give my first Impressions:
1. If we would be lore accurate these are more Exodar Draenei then Lightforged, just saying.
2. Either in the Description here or on the Map would be good to mention what Faction needs to be picked to play as the Draenei(Alliance btw) and maybe show which Heroes are available and what they can do.
3. Recommend to turn the Skins of from the Collection as they override Heroes causing them to lock or show falls Portraits, only the Vindicator was normal all the others were just Frostmourne Arthas with his own kit and the two last heroes looking like Kael´thas and Jaina buth having the Custom Abilities so keep that in mind for anyone else trying it out.
Thats it for now gonna add more when i tested the units.
