Believe it or not, the way your Force Fling would work makes it almost entirely pointless on a damage front by level 6-7 somewhere, just compare your figures to the damage a reasonably focused battle bard can do, and you'll see my reasoning. TKs are in the same category as stuff like Dread Necromancer, Beguiler, etc, they're an uber-specialised caster with an arsenal of familiar-looking yet unique abilities. Our current version of Force Fling actually scales up around 30% behind weapon builds, so the damage is not high, but always worth a punt. Also remember the size of enemies tends to go up the higher the CR, by your system, again you'd not be lifting as much as you may think at later levels, whereas our system again gives options and a good scale. It's harder than it looks to make stuff scale AND balance at the same time, without rather complex maths for both developer AND player.

You may well use a lot of 3rd party stuff, but honestly, if you take away the Wild Talent, then there is NOTHING in TK left which benefits much at all from any feat I dare you to find outside of this thread!

Looking forward to your playtest results, more data is ALWAYS welcome!
