I appreciate all the feedback! I'll incorporate the suggestions for the *some* restrictions for terrain placement for sure, and rephrase parts for the objectives and the coin flips. The intention was to lose the bonus/penalty if you no longer control the objective - though could flip the results if you deal more damage to the Impact Spell than your opponent.
And I thought I had mentioned the AoF - sorry!
As for the 20% cap, that does seem to be a sticking point for a few people! It was meant to be a way to breath new life and force new plans into armies that are well played and loved already, not a point of contention! May have to rethink that approach...
