Pretty much every lightsaber spec gets a fancy "Add your Force Dice to your attack" talent near the end of the tree. Makashi Finish was one of the first that I read, and it seemed pretty amazing. Then I realized Hawk-Bat Swoop has it beat in almost any case, and most of them are at least easier to use, though the effect is different enough that it's hard to compare.
Let's break it down: Makashi Finish makes you extra Vicious, giving you +10 to your crits per pip you spend. Pretty cool, but first you have to succeed with enough advantage to crit.
Now let's take Hawk Bat Swoop. First off, you can use it to close in and start carving fools up. If you're already close, you don't need a successful roll to trigger it. You failed? Dang, well, you still have this handful of advantage to use however you like. If you succeed, HBS will often allow you to crit, which Finish will not, and if you crit, you should have the choice to bump that crit just a much as Finish. Because let's face it: for all but a few special crystals, the best and first mod you should be grabbing is to reduce your crit threshold to 1.
Now, I know that the whole tree is not contained in one talent, and Makashi has a lot of cool tricks. But, dang, am I wrong about Finish? Improvement on one very narrow area of combat, vs more crits, better crits, strain recovery, mobility, and whatever else I want to spend advantage on? Like dual-wielding or Saber Swarm? Yikes.
