Personally, I would rather see them buff the HP and Armor of the Lightning and change the MBTs so that the driver has the secondary gun and the gunner has the main gun (and disallow seat swapping in the MBTs). This has lots of good sides,
- Gives more of a purpose to the Lightning
- Puts the power of MBTs into a (small) team rather than the lone player.
- Would be pretty straightforward for SOE to code the changes.
