Concern: Enchantress heal/pot becoming obsolete?

I was thinking that eventually, let's say we're all level 70, the health of our characters will be overwhelming for an enchantress' heal or for that matter, potions. because the heal and potions restore only a set amount of health and not a percentage of total health, this could cause difficulties raiding dungeons of extremely high level monsters. look at us now, at only level 35, the magic crocodiles are kicking butt and taking names while we heal and spam health potions like there's no tomorrow. just thought that an adjustment to the healing system would be a great implementation, if not necessary, in the future.

I'm guessing bigger, more expensive potions and more powerful skills will be added.

Yeah like pots and skills should heal a percentage of your total health, say like 20% or something, that would work.

I like the idea of raising the skill level cap, that would sort out heals, I'd like to see the current skill effects as well, not just a general one to show the range from 1-5
