Pull more than 5 mobs. Using exact same settings as UF. No issues in uf.
I'm sure its frustrating but I'm going to need more detail to work with. Is it a specific zone, a specific subset of mobs?
I am hoping this is just some bug related to the Extended Targets being messed up. If the wrong packets were being sent, it might have been causing the client to do something weird and lag worse and worse as you aggro'd more mobs. Try it again once EZ has the Extended Targets fix in and let us know if you still have the same issue. If so, I will see if I can reproduce it and figure it out.
I also fixed the guild rank message when zoning/logging in with today's updates.
I am close to having the cursor buffer fixed, but it still needs more work before I can put out the update.
Was able to duplicate the buy now button for aug slot 21. I am still looking into it, but am guessing it is related to the membership packets. If I can't figure it out, I bet Secrets can
I am still not clear on the runspeed issue. Sounds like a custom spell file, and maybe you didn't update RoF2 with the EZ custom spell file yet?
