sweatyboatman, I am sorry. "We" meant players who do not want to waste movement points, and plan their moves precisely. I agree tho, the game is playable as it is. But be honest... this joining/splitting group method is 1. faulty and 2. far too basic for a good strategy game.
(Only the first episodes of HoMM are worse with the calculation of movement points at the start of every round. Want to go far with heavy army? No problem, put a very fast unit to your main hero, click next turn, get a lot of movement points, now exchange the slow heavies from the "buffer" hero, and tadaaa! Go like a hurricane! Geez...)
SOLOSOL, I am not sure... splitting the "unwanted group" on the tile would result in lost movement points again.
With shift/alt/ctrl we could finally step on a road tile with a non-enemy caravan on it.
