Added Rudra's Storm to data and summary posts. Rudra's summary:
Rudra's Storm fTP: 3.25 > 6.6/6.75 > 8.875
Note that fTP scales from 1000 to 2000 TP at at least the same rate as 0 to 1000 TP. This severely mitigates loss of damage due to holding TP (though not entirely, since fTP doesn't affect the dex/agi of SA/TA). In general, total weaponskill damage increases by about 50% going from 1000 to 2000 TP.
Substantially less loss holding TP means that it helps both in waiting for SA/TA timers, and mitigating JA delay.
Also, comes out to basicaly the same damage as Mercy Stroke at 1000 TP, while of course increasing substantially at higher TP.
Overall, lots of very nice benefits for thf using this.
