Fig 1: Without smart-casting, perfect Laser Lock efficiency of 10 missile defenders against 5 targets is only achievable by a small percentage of players. Most players will be less efficient, with the majority of those being the ones who select all 10 missile defenders and attack only a single target.
Fig 2: With smart-casting, the skill pyramid gets inverted. The overwhelming majority of players can achieve perfect Laser Lock efficiency not with just 10 missile defenders against 5 targets, but with any number of missile defenders against any number of targets. Only a small minority of exceptionally bad players will find a way to achieve less than perfect efficiency. The bottom line: laser locking went from being an awe-inspiring skill, to something so easy and trivial that it's hardly worth noting.
