i like you
this is exactly why i used to be a combat engineer main years ago
egrills, shield barriers, rapid table deployment, fake doors, windoors to block boiler gas, encased MG spots with glass on them, NORMAL WALL REMOVAL FOR OPENING FIRING LANES [the dev that made normal walls harder to deconstruct than r-walls, i still dislike you to this day], etc.
all kinds of tactics, all down the drain due to constant nerfs or outright removals
