I use him mainly against ice enemies who love to cast fire shields. The fire minion's bread and butter is fire elf. If the minion were more powerful, I think it would make the wizard/minion combo too overpowering. It does pretty low level spells because you as a fire wizard have access to the second most powerful spells in the game in terms of damage (next to storm). I use to not like him, but learned to use him in certain situations. Second, the fire minion has its pros and cons. Assuming this makes it into the live realm, you will have access to minions from other schools. First, in the test realm, there is the ability to buy minion treasure cards with crowns (not sure if you can do it with gold).
