GMarks should be excluded from military purposes
so everyone who has GMs can produce a lot of units in a fast time but they cannot ie heal them , destroy airfields in use, lower morale of province in a combat zone, destroy buildings in a combat zone and so on
In a current game guy alreayd use at elast 4 mln GMs agaisnt me
In earlier which I won guys used almost 8 mln GMs against me
in a last map I had to adabandon due to fact I was not able to repair my airports any longer - 2 mlns were used to destroy my airports , ground my planes in the middle of the night and make them easy target for arts.... lost half of my airforce durinf first day of fight because of GMs.
so as long as GMs for eco trading spying building are ok, destroying half of army with just GMs is not cool
