i am a passionate engeneer, i really enjoy building fortifications at the position, the only 2 things which kinda ruin it for me is if you try to build barriers around the objective and 1 single stuka attack destroys all entire builds which took me 10 minutes to build… the 2nd thing is the limit of max buildings, (not the building points per engeneer) it makes me somehow sad if i built my dream objective to protect and there is only one more window to cover and then i am not allowed to build more than 10 barriers and it has to remain open 
The stuka is the best is the only cas before drop says (hey bro im arriving)
