There are a few threads in the Light Assault forum talking about how the Jump Jet ability cert upgrades are not working correctly, so I decided to record a video of me gradually dumping 800 certs into it as I ranked it up from level 2 to max level 6. After unlocking each level I demonstrate the difference in height reached and the full recharge rate. As you can see there is only a very small improvement between levels 2 and 3, and then an apparent *decrease* at levels 4 and 5, and then finally level 6 showing a noticeable improvement. In all cases, each unlocked level falls seriously short of what the tooltip claims. The video isn't perfect, but I think it clearly shows that the cert upgrades for this ability are bugged. Note: I decided to be "paranoid" by changing classes to infiltrator and back to LA after each level unlock to ensure that I equipped the latest Jump Jet ability on my character. Apologies that the video is a bit long since I fumbled around a bit with this after the first unlock. The fact that we do finally see an improvement at level 6 shows that it was updating the loadout correctly. This step was probably not needed but I wanted to be sure since I only had 1 shot at making this video. In addition to all of this, another bug seems to be that the height you can reach with Jump Jets appears to vary even within the same rank depending on some external factor, possibly due to client framerate or server load. A number of people have posted about this. Here is a previous video I recorded showing me reach the platform with only rank 2 Jump Jets, which I was unable to reproduce in this latest video until I unlocked rank 6 Jump Jets. Not sure what's going on with this yet. I'll try to do more testing later. Finally, I also wanted to mention the most serious Jump Jet bug where the entire ability can completely stop functioning altogether until you actually log out of the game and then log back in. This is a really nasty bug since it forces me to completely leave the game just to fix it. I'm not sure what causes it yet, but it seems to be related to dying as another class after using the special ability of that class and then switching back to LA when respawning. I seem to run into this the most as Heavy Assault, although I think I've seen this while switching from other classes as well. I hope this post helps bring some attention to these issues. Thanks!
