Connection Errors and Unplayable Lag

Ever since 2.15 I've been getting a ridiculous amount of 90k and 2002 errors. I get a minimum of 6 in a single day. Sometimes the game plays fine, but then I get unplayable amounts of lag. Everything freezes save for idle animations for several seconds. I've seen it go on for as long as twenty seconds at a time. And I've had episodes where these ridiculous lag spikes go on for several minutes. I know it can't be anything on my end, because I have other MMOs on my computer that play with literally 0 lag and connection errors whatsoever.

So I'm here, seeing if there are any answers to be found. Thanks.

They dont even acknowledge it, thats the worst part, Im getting extremely fed up with it. Things like Titan HM which is easy to me at this point, is now hard because I lag so bad.
