Yah, the Leg Sweep + Heavy Thrust combo I figured out, and it's pretty handy for soloing. Getting in the Heavy Thrust to start the fight off isn't too hard either.

I'd disagree about using the Vorpal Thrust combo before level 26. Each hit of ID does 5 more damage compared to the average damage of the combo. However, if for whatever reason you fail to do it, you've lost 75 damage. That means if you miss it as often as 1 in 15 times, you're coming out behind. Even assuming a perfect tank, there's still AoE dodging that can throw you off. And that's assuming a perfect tank.

Just not worth the risk, in my opinion. It's biggest selling point is not so much the extra damage, but the ability to 'interrupt' your combos to place in a non-combo move. Once you use True Thrust, you're kinda locked in on what your next attack is, and can't drop a Straight Shot or Heavy Thrust. Sadly, ID will sit on the sideline until I get it's follow up moves, even without Full Thrust.

Oh, and I tried to mention this in an edit because of the posting limit, but I guess it wasn't seen. What is the exact condition for gaining the 50% "Higher level class" bonus? Is it merely enough that you have a single combat class at a higher level than your current one, and you get the full 50%?
