Nice work Morts - lovely to see a recent post!
One of the things I like about MA/A is its simplicity - because you can tinker with impunity! A few thoughts on your ideas:
Dodge - what's to stop dodgers to melee more stoutly? Maybe stipulate vs missiles only?
Double attack - n ot sure I understand this, can you give an example?
Long Range aim - brilliant! This should supercede the existing shooting command.
Hidden ambush - perfect! I'll use this in my next game with my wily Picts.
Die Hard - could make a super troop type and that is scary!
Intimidate and goad are powerful as you delineate them and happen to be immersed in a reaction system I would prefer. But tell me how you get on.
Sneaky shot - powerful. Again I would apply this to skirmishers alone and probably not the iceberg throwing frost giant unit!
You playtested these Morts?
