Spawning as a Scout or Logistics, throwing Uplinks everywhere, and swapping to a different suit such as a Sentinel is simply too powerful. Let's take a look at two different play styles of the Support Logistics and the Sentinel.

*Sentinel: Heavily armored, moves slowly. Has the highest DPS in the game with a weapon that has short to medium range. Primarily meant for point defense or for attacking a specific location to break into the enemy's base.
*Logistics: Weaker armor than that of the Assault, slower movement. Faster than the Sentinel but has FAR less HP and FAR less DPS. They carry additional equipment to help their team. In short, they give up a lot to have those extra equipment.

Now imagine the balance nightmare of a Sentinel that dropped 2 Uplinks and 4 Triage Nanohives. You have a Sentinel that is no different than a Logistics really. In short, you would be doing two roles at the same time that need to be made completely separate. It lets the developers begin balancing things from there.

I don't really follow the idea of "I am Superman; I need to be able to put Uplinks because my team is worthless!" So many people have said the same thing that with our very small community it is likely that several Superman are on the same team. You can still run in with your Scout to drop Uplinks to help your team get back from the Redline. I don't see how "I need to be able to do everything!" is an acceptable argument against this change. Remember that it affects your opponents too. If they all go Sentinel to hold off a push, no more Uplinks.

It will be a different kind of game. I don't see it being the end of the world or any kind of hyperbole.
