Take a look at a bf2 Inf-Only Server...
Most People are jumping around as Medic, spam nades and medpacks.

They don't need no taktik, because they have a unlimited supplies of Medpacks.

Giving every class a Medkit promotes the same behaviour - bunnyhopping assaults, spamming nades and using Bacta if needed...
Thanks to DICE the 2142 Medpacks works different than the BF2 counterpart. You must stand by a medpack, not only run over it.
So it's sensible to drop the medpack at a good place with cover and defend this position.
(In FS you can make this positions even stonger by building up a shield and an gun enplacement)

Giving each class a medpack maybee sensible if you introduce a Bleeding System like in Project Reality / AiX / Forgotten Hope or Battlegroup Frontlines.

But a bleeding system (slowly dropping health after a hit) switches the whole Feeling of the Fights - Instead of "running around and shoot, get shoot, take cover, shoot back" it will be a "run around, get shoot, run away, hide, lick your wounds"...

And frankly speaking - a bleeding system is a very simple "reality damage system". A shoot may cause a wound that makes your arm or your leg useless.
Forcing you to drop the gun an use the pistol ( even in the wrong hand ) or slow down your movement. This effects are more serious and common than bleeding to death...

CYNIC, n. A blackguard whose faulty vision sees things as they are, not as they ought to be. Hence the custom among the Scythians of plucking out a cynic’s eyes to improve his vision

Heh, stop describing me...

Wait...  Is there going to be anything similar to vanilla's supply drops eventually?  If so, I will back down from my stand on bacta vials.

*Too add to statement's factuality, an extra comment was inserted.

(Edit) Woo, 100th post!  What better way to celebrate than to do this damn term paper...

(Edit)

Actually, a bleeding system sounds like a good idea.  Whenever I've played a game with a bleeding system, the realism made it pretty kickass.  Usually I wouldn't allow myself to fall victim to the bleeding anyways, but the enemy tended to succomb.  But being unable to fight due to losing arm abilities kind of ruins the last stand that we all so love to make.  Slower movement, I'm sort of split on.
