From what I've seen over nearly 9 years playing this game, the original Puncturing Strikes and its morphs is an extremely favored skill in the game. Players love how it looks and feels to use, it's not like Dive on Warden where it's the only spammable the class has; players like the skill. It could be nerfed, and the skill animation could be sped up to .8 seconds, rather than reducing the number of hits and changing the animation. I don't think changing the animation of a player-favorite skill is something that should be done. It's something that should be done on skills where players absolutely hate the skill animation or how it feels to use;
players love Puncturing Strikes, how it looks, and how it feels to use. Nerfing the damage a bit won't change that.
An example of a skill players very much dislike is Warden's Dive skill and its morphs. It's slow and doesn't feel good to use, and after its nerf, it's pretty lack-luster now. THIS should be a skill worth looking at animation changes, not skills players adore.
A good example of a skill that was worth changing is Flurry and its morphs. I have not met many people that like flurry's original animation or how it felt to use. The new animation is a bit lacking, but the intent of changing the old one to something that feels better to use is good. And it does feel good to use now! Though it's a bit slow for the theme of a flurry of blows, and the animation is definitely either the light or heavy attack animation for dual wield, so the skill itself does deserve its own unique animation that follows the theme, or at worst a re-name. But otherwise, I like the intent here. It shows that the devs were listening to the players, a majority of whom did not like this skill and how it felt to use. It's not perfect. But it's better than it was.
But again, Puncturing Strikes and its morphs do not need a new animation. It wasn't something players were asking for. So please, I implore you as one of your many Templar players; do not change this skill, and please do not change skills players love. At least, don't change how they look and feel to use without extensive player feedback on it. There is a case to be made for improving animations in this game, even ones on skills players adore. But I believe if that's done, it should be done in a way that players can give feedback on the skill change over a period of time and give improvement ideas. Currently, it's just being changed with no intent for this kind of feedback. These are skills we are using every day. Main spammables especially are the skills we see the most often. We should be able to give feedback on this, so it can either be shelved for the time being for improvements and changes to the animation, or so it can be scrapped if it isn't going in a good direction. Adjustments to damage numbers are inevitable, but fundamentally changing the skills players love is not constructive.
My comments on the animation change and how it could use some work (from the POV of a professional animator):
