Feint is probably one of the worst Lancer skills. The only good thing about the skill is that it never misses, but with the new accuracy buff you won't need this skill.

Also it does a lot less damage than other Weaponskills. I tested it on Roadrunners (55-59) and Feint did ~440 damage while Skewer II and Moonrise II did ~650 damage.

Oh by the way, you can also forget your Doomspike II unless you fight a lower ranked mob, because Chaos Trust did a liitle bit more damage (on 2000TP) vs Doomspike II (3000TP) and when the enemy was below 20% it did 50% more damage than Doomspike II.
