Probably Ankaur Maro-ing an old topic here but...
I know we often talk about potential factions and other units for existing ones, but do we take enough time to talk about what other game play aspects of Runewars could be implemented in the future?
I'm talking things like:
Boons (we've had vitality), banes, conditions (they were introduced with DK's).
Unit types in general? (Obviously we talk about flying mounts - but how would they work?!)
More in regards to Magic and Runes (This stuff is a pretty huge part of the Lore, which we could then get into in regards to novels etc)
Rulesets!
Organised Play Stuff.
There are lots of conditions and things from Descent that could be translated over. I personally like to think they'll introduce Giant Minis that cost lots of points and will result in an "Epic" Variant which means bigger board and more points.
Stuff like dragons could then maybe burn multiple units at once.
I've seen people talk about Poison bane.
Let me know some more ideas that may have been missed or you've kept to yourself!
