Loss of drain on Blm...really?!

[Archwizard]

So far for this topic I've largely seen two very distinct positions:

1) The group that is considering Drain as it was in its form as a role action, and doesn't care to see it return to BLM because of how pathetic its output was compared to the damage loss.
2) The group that would like to see BLMs get some form of self-sustain for crisis scenarios and questing, and think an iteration of Drain would be a thematic backup to Manaward.

What puzzles me is that most of what I've seen of Group 1 thinks itself mutually exclusive with Group 2, even though both positions can be simultaneously satisfied by just not giving BLM an 80 potency attack with 80% damage-as-healing.
In all honesty, I expect half the reason it was so weak to start with was having to balance it against Ruin.
Give it something like 200 potency and 150% healing, that at least would be semi-worthwhile healing without replacing a healer. Sure the damage would still be pathetic but it's not like the intent is to be part of the main rotation; you don't use Sleep in raids either.

Bonus points if you remove Scathe and make either Drain or F1/B1 instant.
