This commander is fine except for the 'Anti-Building Flame Mortar Support' ability. It's use is so incredibly specific and limited that most of the time it can't be used, or is a relative waste of ammo for what it achieves.
As several factions have flame artillery call-in I recommend renaming it to 'Flame Mortar Support' and making it a standard area denial incendiary call-in. I understand that people might have wanted to make this more unique and different to existing call-ins, but in its current state the change simply makes it much less viable, or effective in the few instances it can be used.
