I'm surprised that the numbers we were working with were so far off - the wiki said the old delay was 0.35 seconds, but after reviewing some videos the 0.5s does sound a bit better. I don't know what it is, but the change seemed a lot more significant than than 0.3 ish seconds, idk why that is (Well, 0.3 seconds is a 60% increase over the former 0.5). Maybe I had just played too much Xerath.
Ah well, very glad to hear that I'll be able to play Xerath again, and show off the new skin.
Thanks again for the reply!
