Yeah, that sucks.
Long version:
The problem lies in having the ability "Blood Frenzy". This ability grants you +5% damage per 10% missing health. That said, at 100% you would do 0% more damage than usual. At 50% health, you'd do 25% more damage. That's, at least, how I figure it. I assume that the God Mode puts your health at like 9999999 or something. If your health is(with God Mode on), for example, 200% of your normal helath - that would mean that you do 50% LESS damage than normal. Let's say that you have God Mode on and your health is increased by 1000%, ten times your normal health, that would mean that you do 500% percent LESS damage than normal - which could resuld in you doing no damage at all, or as in your case(and mine), you do one damage. Which seems to be the lowest amount of damage possible to do per strike.
I'm not very good at math, so bear with me if there's any mathematical incorrections.
Short version:
I would suggest(at least until a fix for this "bug" is released by Mr. Antifun) that NO REAVER picks the ability BLOOD FRENZY and at the same time use GOD MODE. This will result in you doing one(1) damage ONLY, except for some combinations of abilities that results in massive damage.
My suggestion to you, our esteemed Mr. Antifun, is to put an option in the trainer that actually LOWERS(and locks it there, of course) your health to, let's say, 10HP or something. That way, we reavers would do MASSIVE damage instead of 1 damage. Anyways, you're awesome, Antifun! Keep it up!
