100% Toughness Regen makes not up for Heavy attack Toughness back

The Toughness Regen Delay is too long and it does not make up for Heavy Attack Toughness back. Heavy attack is still far better but like i mentioned in my other post, with Slabshield you cant get it up fast enough without loosing it again. Evfen when you have the Feat on top with 100% Regen on 25% HP, the elay kills it all the time!
