What I find most interesting though is that when using the Underfoot client, after hundreds of zones into T10, I never once saw a grey bug. So if there's a way to simplify the fix knowing it only has to address RoF2 hopefully this info is helpful.
I logged in this morning to test T10 using UF client and RoF2 client. Here are the results:
UF Client (5 Attempts)
12/12 - 27 toons in the zone including mine
12/12 - 27 toons in the zone including mine
12/12 - 27 toons in the zone including mine
12/12 - 27 toons in the zone including mine
12/12 - 27 toons in the zone including mine
RoF2 Client (5 Attempts)
10/12 - 12 toons total in the zone...all mine
10/12 - 12 toons total in the zone...all mine
9/12 - 13 toons total in the zone...including mine
9/12 - 12 toons total in the zone...all mine
9/12 - 12 toons total in the zone...all mine
Decided to load up UF Client and try again...
UF Client (3 More Attempts)
12/12 - 12 toons total in the zone...all mine
12/12 - 12 toons total in the zone...all mine
12/12 - 12 toons total in the zone...all mine
So.. results for me using UF Client... 0 desync's but with RoF2 Client...various desync's. I would have to agree with Blurring, Chunka and others that say the RoF2 client seems to have the issue with desync's in T10. As to what is causing it.. I have no idea. Maybe its how the clients address the server packets being sent upon zoning in. Again.. I don't really know anything. One thing I am 100% sure on both clients is that the mobs rape me!
I hope this helps and there is a fix for the RoF2 client for T10. As of now UF client is the way to go for stability when dealing with T10...but I am not sure I can go back to using UF client again after being exposed to the awesome features that the RoF2 client provides.
