Could anyone explain plainly and shortly the change in the thing with tactician?
All effects that take place after firing now occur after firing the final volley of a multi-step attack, once.
So now if I make two attacks (last one granted by gunner) I only give one stress.
It´s that it?
No. Tactician/Gunner still works as normal. Tactician/TLT or Cluster Missile is what's changed.
ARC can do Tactician/R3A2 which is double stressing.
