The T4 on the calliope is actually more harmful than helpful now, since it can't cancel or anything while firing. Makes it so that it's more vulnerable for a longer amount of time, while most things are going to move out of the barrage by the time the 2nd volley of rockets fires. Not saying that the calliope should get some kind of buff, I just think the T4 needs a total revamp.
50% more rockets will make 88mms cry, support weapon teams dying more often, and Pak Guns take more damage. Maybe even the occasional immobilized tank taking more damage than usual. Though I agree, the T4 just needs to be revamped.
The first 2 doctrine ability of the tree focuses heavily on vehicles. Then out of the blue, it suddenly switches over to the Calliope. Maybe we can have a vehicle based T4.
