t has come to our attention that the WOL client often gets stuck while uploading a report after the 5.2 patch. After looking into the issue, it turns out that the 5.2 combat log changes cause the client to use much more memory than before. This can result in it running out of memory and getting "stuck" while uploading.

We are working on updating the client to more efficiently handle the new combat log format. This requires us to change the way the combat log is parsed and compressed for uploading. In turn, this requires changes to how our servers read the uploaded data. Due to the complexity of these changes, this is taking a little longer than we'd like. We hope to have a patch ready for you by tonight.

Здесь и утверждалось, что чем дальше находишься от спавна зелёнки - тем меньше урона прилетает.

It may be worth noting though that one of the world bosses, Oondasta, is intended to be crazy-difficult. If you’re not in an organized Heroic-level raid group and teaming up with other Heroic-level raid groups, you’re going to want to stick to the other world boss, Nalak....

Let's just say that Oondasta is going to deliver on the rare and tough design we wanted from Galleon. We are prepared for tears.
