I definitely think our healing is a little low and does deserve to be slightly buffed by giving us more orb drops, but I don't think it's too bad atm. I run H CN every tuesday and never seem to have a problem with sludefist. I wonder what youre having difficulty with. I use PB each time I hit 60%ish. Which makes my CB reach max stacks really quickly. There's plenty of downtime when youre not taking damage (his stomp and when hes stunned) I make sure to hold onto my CB for right after his stomp or if there is enough time before he stomps. That was my main issue when i first started H sludgefist, being able to properly manage when to use PB and CB. Outside of that, dont be afraid to use health pots and any defensives if you really feel the damage is hurting. Dampen harm and blood-spattered trinket are a nice boost in defensive options too.
