I noticed it in my last few games playing diana jungle. Just finally realized what was causing it. If you are attacking and pop a mana or health pot it actually slows down her attack speed significantly. I tried to re enact with health and mana pots both did the slow down. Should probably take a look at this when you get time
Ah shit, I knew I wasn't imagining it! I was doing a custom game to see how Sated Devourer jungle Diana went and I noticed once or twice that my AS went down a lot. I'll check this again and post a report as well later I think.
Thought this didn't post the first time...so i actually made a duplicate post...oops
But ya...its pretty noticeable.....happened in jungle and dragon..didn't test it vs lane mobs though
Quick update: popping pots only slows down attack speed after you get Devourer
