Sag, very cool and generous from your part. Nicely done.
Regarding Ironite and rankings:
The only ranking that matter is Saturday´s at 4pm PST, you can save your ironite during the week and make a run in the end of it. The current point system favors this strategy.
Offense:
Health + Healing + Shield + Revive + Patience.
Defense:
Health + Disabling + Damage. (And you need testing as Sag mention to see if the champions work well together)
