The helheart set breaks acheron and post tweak isn't the superomgwtf gear it was.
Unfortunately it's still very strong.
Levelup points all dmg, level 175 dmg buffs (be, fu, ea, ef, if, es) at level 900:
Acheron + best dmg gear: 3430 att 21405 dmg (with volkers, 5400 att, 21200 dmg)
Helhearts + azure + best dmg gear: 1918 att 22435 dmg.
Net difference -1512 att +1020 dmg.
Throw in KE175 and DC175 and you can beat 3900 defense reliably - and that covers 54 out of 72 creeps between 900 and 968 - only 18 would pose a problem (some of them would reduce the dmg bonus to about half, because best ring/armor/boots with attack all seem to lack about 400-500 dmg to the best dmg gear).
So, for a big majority of creeps, these two sets together mean that you can save either be350 (175 is enough) or EW1500 (EW1000 is enough) - and on the tougher creeps, it will knock off one level of CA (DBL1200) or 2/3 of it (DBL750).
So, unfortunately, helhearts is a MAJOR hunting set, with a big impact on levellers. For a big guild, it will pay off even at pretty serious prices - as it makes 1hitting cheaper.
