Gameplay Problems

So, I’m not sure if everyone is having lag problems, but I am. I just made a worgen rogue, because I haven’t done either of those in a while. The first thing I found was that when I went to loot something, it would delay a few seconds before bringing up loot, then it would be a few more seconds after I clicked before I got the loot. Also, the ride on Crowley’s horse was terrible. I could barely control it, and it would run in random directions without listening to my commands. I couldn’t get off of the horse, so I logged out and logged back in. I was off after logging back in. I’m not sure why these problems occurred. There isn’t maintenance until the weekday, and I’m not sure if gameplay is even affected by that. If anyone has any idea why this happened, I’d like to know.
