Current impact of Damage Over Time in battle (since level 80 cap and Fortified Health)

I think the problem is that DoT's are still based on max HP, but with the introduction of protection the actual % of damage compared to effective health (HP + Protection) is so low it is now even less useful then it was before. That along with them still not being able to change it back to DoT's being able to kill, leaves characters with DoT's at a significant disadvantage.
