Hold the Line is good on paper but in reality spending 250 muni on this ability is just terrible because the planes (which make the ability so expensive) arrive very late and if the enemy decaps territory or moves out of it the planes will never arrive which means you just spend 250 munitions on nothing.
In sort you agree with my point that the ability needs a redesign (regardless of your reasons) and that is fine by me.
(Although UKF with -20% received accuracy can defend a sector for few seconds and the ability does not trigger only 1 sector but multiple.
And cap mechanism is in line with other similar abilities so nothing special here. What is special about the ability is that it targets all enemy units in all front-line sectors with planes)
It's basically clicking the button and then hoping the enemy doesn't move for 10 seconds so the planes can be triggered. It's just too hard to pull off to make it worth it.
Not really. It choosing to active the ability when you are confident that will be able to defend at least 1 front line sector for a few seconds.
