The Campaign mission 'Tipping Point' has become impassable due to the combined effect of the Mortar accuracy and the new Fatigue/slowdown System.

I have attempted the mission over 30 time in the last hour and a half and in every one I either die or the whole team gets wiped out due to their slow pace.

Those that make it through the barrage get efficiently clean up by the paratroopers. and this is only the first wave.

I play on normal.

In conclusion:

Mortars need to be toned down, less paratroops. Generally I higher level of survivability is needed.
