More experiments with gamplay changes are always good
And if its just changing values then just trying it out is quicker then long discussions.

make skirmishes (fights in the middle of the map) longer, instead of during less than 10s in average

How about just reducing the damage that is dealt? Players wont die as fast and need more time to kill enemys.

yes
the problem is also that building wrong is punished hard the longer a game goes on.
A new regression since tremulous is that its possible to feed with buildings and quickly lock or lose BP.
