Lower the TP cost on Piercing Talon

[Altena]

In its current state, Piercing Talon currently has very little use. There are more negatives then positives to PT which start with-
- Interrupt your combo
- Very taxing on TP
- Currently very weak (even weaker then True Thrust).

While the "positive" is that it is a ranged attack, the utility is definitely outweighed in this instance as rarely (if ever) it is not optimal to use it at all.

Ideally the skill would be useful in situations where you have to run away for a brief moment, or stand at a specific point, away from the boss for some kind of mechanic (which is a very frequent case), however due to the weak potency and huge TP cost, it makes it pretty much pointless to use in fights where TP can become a tad tight.

I don't believe this will unbalance DRG's damage as the increase will be very slight (120 potency attack every now and again more then what they could have done), but at least it would create a purpose at endgame other then pulling mobs when solo'ing quests.

Myself, and many other DRG's from 1.0 probably remember how useful throwing spears were in 1.0, (mainly for TP gain) but as a whole, using them was more "fun" then not using them as it let you be a little more creative on your playstyle.

So please bring back the ability to use these low potency, ranged attacks in end game content.
