Actually no, we don't need jump suits or jet packs. Both of these proposals have been pitched before, by numerous posters and every time these proposals have been roundly opposed by the game community.

The issues with jump packs/suits are as follows:
1) Currently the dropship is the only point of entry to high locations. By removing the DS's only usefull ability you would essentially be removing it from the game which no one wants.

2) This would lead to even more annoyance with snipers in truly stupid locations. It would be a pain and we don't want to deal with the "I'm in the impossible to hit location that also conviently lets me totally cover that objective" play style. This would make the game much less fun for all of us.

3) People jumping about in combat is annoying enough, imagine how bad it would be if they could fly out of combat.

4) I didn't see if your scheme for these devices allows for weapons use while they are being deployed but imagine how much more it would suck to be mass drivered by people hovering over your heads.

5) How are you going to balance flight time vs costs of the units or are you proposing that people be able to fly around non-stop? What about an overheat mechanic? Is there a chance the units self destruct?

6) Jump suits/jetpacks will in no way actually improve the game since it would not add anything new beyond annoyance which would only be new in that it would be a new flavor of obnoxious.
