Something like this has been suggested before, but hear me out - i think this change could actually help balance issues a lot.
Right now, the jetpack is useful for one thing - getting to places on the map that would be hard to get to or unreachable for humans. It's slower than running and much slower than sprinting.
Basicly my idea is to make the jetpack quicker and and easier to maneuver, but limit its ability to fly for long periods of time. More of a "booster" than a jetpack, it would be activated and boosting or off and recharging, and could be used in spurts, not toggled and move slowly in any direction.
Why?
Balance Issues -
Why can s2 aliens manage to hang on against s3 humans until they reach s3, and then quickly dominate?
as soon as aliens hit s2, the builder class can reach anywhere on the map
quickly, and egg spam etc (think transit). Humans stay busy hunting down eggs, but the adv. grangers get away from the humans easily and place more eggs....
Even humans with jetpacks cant catch the adv grangers, because the jetpacks are so slow...
lets reverse the situation, s2 humans against s3 aliens. the humans will probably make it to s3, hold off the aliens for a little while maybe, and then get eaten by tyrants. they will be trapped in their base for most of the time. Their only chance is if one or two players can sneak to the enemy base and destroy the eggs while the aliens are attacking the human base, and hope they didnt have any grangers. But this almost never happens, because aliens move so much faster that they are bound to cross paths with slow-moving humans.
In short -
* Faster jetpacks would give humans a chance against tyrants by allow them to outmaneuver or escape = more goons, less tyrants - cool.
* humans could possibly escape and rebuild base the way aliens can
* goons could still handle jetpackers - the jetpackers wouldnt be able to stay above goon pounce range for as long, and the goon pounce would still be a bit quicker than the jetpack boost at full speed.
* no more jettards (you know what i mean) - jetpacks are now actually useful for maneuvering, not just travel and hanging out above ATCS spamming.
* it would be FUN! the best thing aboubt playing aliens is the speed they move at... why shouldnt humans be in on the fun?
just a thought...
