No, I'm not saying that. I'm saying that there is little reason to include a "heal-miss mechanic" because it is nonsensical. Like I said before, it makes sense that weapons have a chance to miss because pilots tend to try to avoid incoming damage in battle. This doesn't apply to heals--they aren't trying to avoid heals, so there's really no reason they should 'miss' or have a chance to miss. I don't understand why this is so hard for you to recognize.
And I am saying if you are trying to avoid being hit lets say EM plus EPtE why should a heal land on you 100% of the time?
