Season 6 engineer rework

For me - unless there are changes to current engineer ammo levels (through availability of supply stations, or enough initial ammo to actually take out a vehicle) WITHOUT having to rely on someone else dropping ammo, then the engineer gadgets all need a major buff.  I'm sure DICE have much more changes planned than a simple buff, so I'm hoping for static supply boxes, the ability to call in ammo drops, introduce IRCCM (InfraRed Counter-Counter-Measures) weapons.  I'd also like to see tweaks to lock on times for Stinger and Javelin as they are too long, stop locking on to empty vehicles, and instant lock on for tagged or pre-targetted vehicles.  Instant laser lock on rather than auto aquire would also be much faster and more accurate.
