Soo... about WHM Tetragrammaton.

[Ghishlain]

i didn't say it was worthless. i just don't see it as a big deal skill for a lv60 end game skill. should have a bit more potency atleast

Does a level 60 skill have to be amazing? I don't think so. Look at Dissipation and Celestial Opposition. Out of the three level 60 healer skills, Tetragrammaton is certainly the most useful.

Just consider it another tool in your toolbox and use it appropriately. If you can't appreciate that, I don't think there's much more than us, the healer community, can tell you.
