The skills are way too OP for a ForceMaster. It's a no no for me too. Well with the exception of the 4th skill of course. Which doesn't really matter if it will be added or not.
In response to what poonboy has said, I'm sorry to disagree. Though one thing I agree at is that ForceMaster could be a boring class. But even though, players still enjoys playing it especially in the arena.
The reason why I disagree on the Soul of Rhisis being added as a FM skill is that it will make FM more invulnerable. We all know that a full STA FM (without rarities) HP's could go at least 710 M in the minimum. With that being said, Harlequins and Mentalist (the two mentioned top classes) still have trouble killing it. And with the addition of Rarity scrolls, it is still the same issue. And also, you based your idea on a glass cannon FM. But what if it is a FM switcher? You already said that FMs can have an enormous amount of HP to survive main PvP skills (HoP and Aether, I assume). So having Soul of Rhisis on their arsenal, like I've said, will make them more harder to kill.
I'm pretty sure you've played FM before and you know how to outcast in mid-air while the Asal is on CD; I'm not sure if that will work against Harlequins and Mentalist but the point is, they are not that vulnerable.
If and only if Mazey will consider to add Soul of Rhisis, then it will be balanced if he will reduce the HP gain per STA of BPs just so it could be killed by a Harlequin's sole HoP. Because as of now, Harles need at least two Pandes or one Pande + HoP to kill a STA FM without rarity scrolls.
