The chariots played a crucial role in the Thrawn Trilogy, their destruction being a part of what caused Thrawn's displeasure with Nile Ferrus and the mistrust of Talon Karrde that did lead to Thrawn's death. However, they, kinda suck in gameplay.
So I propose a minor buff. They were used as command vehicles according to the manual, so why not add a function for them to carry a squad or two? Considering that in 2.2 commanders will be reintroduced as basic infantry, I don't see any problems with this.
As a side note: Can, we get a Juggernaut revamp in 2.2? At the very least increased health, it's made up of tissue paper for something so long and expensive. If not right out making it the ACTUAL B5 Juggernaut instead of the B6.
