I had an interesting idea for the assaults jet pack. In Starwars Battlefront, the jet trooper has an interesting control for the jet pack. It allows you to travel up as well as horizontally. I was wondering if jet pack controls like that could be implemented in the next update.
The only thing I would say is that it was upsetting to find you cannot use charge vertically (like the tank) instead of just on a lateral plane, but the assault has plenty going for him as it is and is top candidate for nerfing so far as I can gather from reading posts on the forum. I suspect it would be wise not to improve him further
If youre after height try bomb jumping. Apart from that there is not really much need for you to do so as most jump pad areas can be jumped over without having to buy it, G3 turret nub anyone? I suppose it would be fun to just blast straight up if youre getting shot though.
