I do have to disagree with you a little bit here - flame pred's invisibity is the best in the server barring the completely invisible AND it can't be dispelled by flashlight. While I don't really agree with Hyper that it's useless, raps is definitely worse off than flame predator. Setting an enemy is actually an extremely useful skill - it slows down the enemy (which is the best part about) and it also somewhat kills the vision, so that you can jump high after that and go down and kill the victim. Dropping the gun is also a pretty useful skill, although not quite as good as flames. I do agree with you about the ulti somewhat - it's not really that good and I barely ever kill people with it.
Now, for raps - flickering shadows are nearly useless and while they do give an advantage, it's extremely minor. The crit barely ever works, so it's not that useful and the ultimate is... Eh at best. It does have a better levitation than flame pred, so that's a plus for raps. As far my comparison:
Raps crit < setting a person on fire
Flickering shadows < invisibility
raps levitation and speed > flame pred's levitation and speed (barely)
invisibility = nova (although I do like nova more as ulti for flame pred than invisibility for raps)
For me, flame pred definitely edges out rapscalion by quite a bit.
It is somewhat useful, yes, but can you compare to most of other ultimates around?
Fair enough about that.
As far as jack's KDR goes... I'm fairly certain you'll see it go up once more people will max it and whore it. Yes, kdr is not everything... But it definitely has some truth in it and raps is a fair example.
High amounts of level = a lot of xp = juicy target. Thus people tend to concentrate and look for you (I've seen it quite a bit), thus your life is even harder.

Actually, really depends on a race I play - I play super aggressive with santa, molecule, spider, flame pred, normally jack too. If I'm playing a defencive/support class, then yes, I normally play very conservatively. And night elf? lol. Raps is better of being aggresive with health, cloak, lace then defencive, to be fair...
