So I played around with the Icarus jets last night after the patch. I didn't bother with a progression, and I just dumped certs into them until they were maxed out. I friggin love them. First off, they're not quite like the regular jump jets. Consider them more of a surprise tool. Where you were restricted to preparing your encounters ahead of time with the jump jets and carefully climbing to your perches ahead of time, the icarus jets simply hurtle you into the sky. They're rather unforgiving if you miss your target landing spot, but the energy regeneration is enough that you will be able to save yourself before you hit the ground. The thrust is powerful enough that if you only have a fraction of your fuel left you can still make a quick hop up (usually about 1 story). I was getting massive amounts of fuel regeneration last night.. This could have been a glitch caused by the server latency, but I like to think that this is the intended regeneration rate for maxed out jets. It seems a bit high considering how effective they are at getting you upwards. You can still employ the tapping movement method that you could use regular jump jets for to get from ledge to ledge, but you need to be more careful since the fuel gets consumed so quickly you're relying on the regen to keep you up and your forward movement and momentum between bursts to keep you moving forward. In a smaller scale, if you're getting walloped, the icarus jets can get you out of a doorway in a split second compared to their jump jet cousin. So, despite some meh-saying i've been hearing on the forums, these new jets are awesome. They are NOT regular jump jets and they're definitely not drifter jumps. They are great for getting around most bases and getting the upper hand on your opponents on the fly (pun intended). or for getting out of hairy situations quickly.
