Guardian of the Sands Xerath sound effects are different from before this patch.

Played a game last night with my favorite artillery mage, and noticed that there is a slightly obnoxious sound that now accompanies his autoattacks that was not present before the last patch. It's...... kind of a mix between a whoosh and a voip, difficult to describe, but very noticable on every auto. I'm 100% blaming my inability to cs on it. The sound seems similar to the other SFX, but is significantly louder, so i'm unsure if it is new, or or an old sound that somehow got its volume bumped up, or its intentional and has just never been on.
