CTP is one of the few abilities (together with stuff like Combined Arms) that are actually well designed in the sense that they can be really powerful but have a set of requirements in order to be activated. Much better than all the click-and-forget abilities like airplane strafes.
It's quite easy to prevent CTP by building caches and even if the enemy pulls it off it's quite easy to avoid it by quickly retreating your army (targeting is slow so nothing or barely anything will get hit) and take the cut-off back as soon as possible. I'd say the only real problem is that many players simply don't know how the ability works or what it does and don't recognize it when it's being used, but there's not much that can be done about that.
I'd love to just have 2-3 panicking voice lines stacked at once when it triggers. Would alert AND feel good to know the enemy should be freaking out.
