222 is fine as it is, buffing its health or armor would make everyone rush it so it would be the new meta. Early game it's great for supporting your units and even killin lonely squads on retreat. But when other light vehicles come around then you need to start using it as a harassement unit or a scout vehicle due to its good sight range. It does require alot of babysitting but once you have that kind of micro, this unit can even shine late game. If upgraded with spotting scopes, this thing is a hax.
