The Battle Health Regeneration mods still work backwards... we reported this when i was still a rep. I now have -3% myself and it takes 3 minutes LONGER to regenerate 1 hit... it should be

+3% health Regeneration...
or
-3% Health Regeneration Time...

The current math means anyone with a mod loses out. I have taken screenshots showing time.. from empty..1 hit should be available at the 1:15:00 time code... as standard.. 25 mins per hit.. total 1hr 40mins..

I was still waiting until 1:12.00 to hit...
