How do you all determine what situation's best for what mode. Like, in a fire fight i use armor I think it's best but how do you know what situation is best for the stealth or speed modes?

I feel like sometimes I whore the cloak mode and then dont have enough suit power for fights.

Cloak for movement around the map & reloading.
Armor for gun fights.
Sprint for map movement, especially when needing to move from cover to cover.

Yes, you need to learn how to manage your suit, first and foremost. If you can't do that well, you will almost always be at a disadvantage. If you are finding yourself out of suit power often, I'd suggest stopping along your way to recharge a bit (if not completely) & then moving on.

Quick question how do you discerne when to use sprint mode over stealth mode?

You'll get the feel for which situation is right by playing, but some good rules of thumb...

In a hallway (or other similar area) where the are only two exits, you might as well turn stealth off as the only places people could come in are either A.) The door you came through (and you just came through there so you should be able to see just fine), or B.) the other door, which you should probably be facing if you just came from entrance A.

Open ground is a great time to use cloaking. Cloak, sprint across open ground to cover, decloak and recharge or if your a beast just keep walking like a boss while recharging.

Always armor prior to shooting out of cloak. Do not shoot if possible out of cloak, in those "OH F***" situations where you weren't expecting someone to be right around that corner, shooting is acceptable and actually preferable as if your "oh f***" reflexes are faster than the opponents "oh i think I see an invisible guy...hey that IS an invisible guy! *shoots*" reflexes. Other then that, ALWAYS armor prior to shooting.

Armor while falling to not take damage.

If you have mobility enhance and armor enhance feel free to sprint and jump around in full armor mode without having to worry to much about suit energy.

And for opponents chasing you...Power Jumping over obstacles is always smarter than running around trying to juke, a player will have a harder time jumping to the exact same points than running to them.
