The supervirus can be pretty sweet. But then again, the moments where it needs to be used, the SCH can just do it. There is no need for a Summoner to use the supervirus unless the SCH is dead. It's therefore not utility, but more of an expeptional situation.
So, from the way I see it:

- Delete battle raise
- Give more ST damage than BLM by upping the potency of pets and Fester. Not by a lot though.
- More sustained DPS
