Consider a more focused class system

The goal here is to improve the current system to present stronger distinctions between sub-classes/training paths and to improve overall functioning of each class. Full disclosure, my playstyle centers around engineer and support classes. I would offer up feedback for assault and recon, but I don't play them very often. 

Engineer

1. Anti-Armor Path:
   1. Replace the repair tool with the missile intercept system from the Support class. Set a minimum proximity between them, like is the case for AV mines. Make them more durable. 
   2. Change the active class ability for this path. Maybe a weapons overload ability or the sentry mode from EA Battlefront 2, which gives the player heavily reduced movement speed in exchange for increased rate of fire and health regeneration. You could make it only usable within vehicles, as a unique spin on the anti-armor focus to the class. 
2. Combat Engineer Path
   1. Replace "gadget fortification" with "gadget awareness" from Recon's spec ops path. It makes so much more sense to have it available to engineers. Keep it available to recons if you want, but engineers are so gadget and vehicle focused it's really quite odd for them not to have some enhanced abilities in this area. Especially since combat engineers are often pilots or supporting those who are. 
      1. (Recon/Spec Ops path) I'd suggest giving them something like the "seeker tactics" ability from EA Battlefront 2's infiltrator class in place of gadget awareness. It spots the 4 closest enemy players temporarily so you can hunt/seek. It could be a cool ability for them to have, especially since they may be more close up than snipers are. 
   2. Lock repair tool to the combat engineer path. It would create a stronger distinction between anti-armor and combat engineers, encouraging players to commit more carefully (but also be more specialized) to their chosen role. 

Support

1. Replace the missile intercept system with claymores (max carry of 1).
   1. Recon can keep access, since both supports and recons are more defensive classes overall than assault and engineers are. Supports especially are less mobile and agile than the other classes, and often set up in vantage points where they stay for a few mins, so it would help to have something to cover their *** with. 
2. Make "steady aim" universal for both support sub-classes. It really doesn't make sense to gatekeep that to fire support while giving the "defense focused" ability to combat medics. It's just kind of confused. 
3. (Combat Medic path) Enable pistol use while dragging/reviving players. You could use this to backfill the now-missing "defense focused" ability, and it would give medics more to work with when focusing on, well, being medics. Consider locking defibs to medic path, as well (see repair tool, above).
