Why is BLM getting a buff?

[Lyrinn]

Knowing how SE buffs, expect it to be a slight potency increase on Thunder, Thunder II, Thunder III, and possibly an increased chance in proccing Thundercloud.

Or revert the scathe nerf.

I would really be disappointed if BLM could deal enough single target damage to draw near to say a monk. That would make the "stack BLM's" problem with this game even worse.

And this is an overreaction on your part. They simply said buff. It could just as easily mean a potency increase of 5 on Blizzard I (lol). In fact, it would be insane to think they would go so far as putting them on par as melee. Why don't you wait for the actual patch notes before condemning them?
