Ched I have gotten some amazing secondary stats on health mods, so keep farming them. If you look at my Rex, most of his speed is secondary from lucky drops.

The only thing I would ever spend creds or crystals on in the mod store is a High 30 speed arrow and only if it wont break ya.

They are so worth it.. it's even best to go back to the mod battles and farm the specific arrow slot so you get a 1 or 2 * direct speed stat of 17 till you get something better.

Same thing with the Potency cross slot for toons that need it.
