You need to get more imaginative!
DragoFireheart's Jagras test was all fine and good, but it was actually biased against the IG due to the fact that I had to harvest extracts as an opener but finished the fight well before they expired. I also didn't send the kinsect to auto-attack and create clouds. A nearly-passive pseudo-DoT dealing 12 damage here, 10 damage there over the course of most of a fight really adds up (to well over 1,000, eventually), and contributes to sever and KO thresholds, depending on kinsect type. In addition, the clouds kinsects create can be struck to deal additional damage (again, depending on type), usually in the realm of 90-120 before the cloud expires.
As for mobility and evasiveness, the IG has tons of it, but largely aerial rather than ground-bound. How useful and "safe" this is varies from monster to monster. If done correctly, you can trash Vaal Hazak's wings (and at the end of the animation, its face) while it's doing its fart nova without taking a hit;, you can continue ripping up Xeno's wings when it does its blue crush explosion without taking a hit; and there are many other examples. When other players have no choice but to back away or get carted, you can flip and spin around like an asshole continuing to deal middling damage (it's substantially less than ground combos, but fast and constant) and triggering kinsect dust explosions. Absolutely no other weapon in the game can run a spinning riot up and down a flying dragon's body while it's fully aloft, for example.
Of course, you can pole-vault over, away from, or out of danger as well. No other weapon can do that, either, so unique tactical maneuvers are available to you.
If you play it for long enough, you'll begin to see what I mean. The mounting aspect of it is of minimal interest to me, actually, although of course mounting is useful in its own right.
