Bunkers Trenches Improved Positions

[typhoon]

It all helps to understand things and it’s always good to see a lively conversation. My contention was based on preparing good defensive positions in advance. With the downgrading this becomes much harder. 
  If positions did not downgrade unless there was a change of ownership it would make me cling to those frontline positions much less stubbornly and make the longer campaigns much more playable long term. For now engineers and corp troops that would be building those defences are thrown into the frontline. The engineers hoping by digging to turn the trenches into bunkers with low % chances. The Corp troops moving up to gain time forcing the enemy one more disruption before the assaults come in.
  This may be a reflection on my own play style but I would like both options to be viable strategies in game.
