I have come to realize that the type of terrain being used has a huge impact for snowspeeders and bike. For example... the job of both units is to swing around the sides and flank dug in troops. However, if your board is made up of lots of linear terrain such as barricades and stone walls the speeders should have a field day in the opponents backfield because those troopers will have no protection and cover from behind.
Now take a board that is utilizing lots of area terrain such as ruined buildings, bases with craters and bases with trees the speeders are almost completely nullified because the troops are always blocking 2 dice for hard cover.
Thoughts??
