[DPS] Storm Glyph vs Exquisite Oilstone

[Trigorn]

So I've been looking around a lot on this and cant find anything one way or the other.
With 1.8 around the corner and scaling going a lot more towards AP, would it be better to get my planar attunement into air to get the Storm Glyph for the 30 Str on my two-hander, or just continue using Exquisite Oilstones and get more strength from planar attunement elsewhere?

10 dps > 30 str from what ive tested
