Seriously there needs to be a cap on mines or something, as I have never seen an attacker win the match on frontlnes. I will lay out the general proceedings of the match as it usually goes.
-we take first objective, push good into second objective.
-Get bogged down in miserable mine hellscape where we can't advance and it suddenly seems the defenders have a huge boost in MP.
-lose match.

I remember playing this in assault squad and that was actually fun, because the defenders had very little MP so they had to get very creative with how they defended. Now, it's a spam of AT miners where artillery all the way in the rear will explode in some random part of the map.

I would be okay with mines if the process wasn't so painstakingly slow and micromanaging. I believe in MoWAS (at least in Robz realism) there were mine clearing tanks that could mop up an area pretty quickly.

tldr: too many mines, defenders get way too much MP, way too many objectives for the attackers to realistically have a fighting chance unless they just spam units, which's breaks the tactical element of the game.
