"Maul already gains Health and Potency in pretty big, possible endless numbers, for which he even doesn't have to be in the lead (again staking the same thing on top of the same thing), "
The added health is always great , I mean when you run out of it in the game you die so having more is a no brainer.
"For which he even doesn't have to be in the lead"
Did I remove his max health from his unique ?
No I added a bonus for 2 brothers whom which one was the master of the other , and now the master who had a Zeta leadership already will now give extra potency and Max Health to them both , and if you remember brute the more debuffs they apply the more defence they get and savage with extra 15% max health is 15,000 more Health for me . Mauls base is 32000 +20% from unique brings him to a starting health of 38,000 no mods not exactly great , if he doesn't get enough turns to stack his health he is normally easy to kill ,more max health helps that. The extra 15% brings him to 44,800 now before mods . And the extra 5% max health steal added to his unique, will now be better sooner .
And the added potency will help savage stick his debuff more on enemies again stacking Ten and Def .
Same with maul applying a debuff on his basic he will stack ten and Def , on top of what I said before it works. unless he is still fighting 1 Vs 5 for you ;)
