Every day at the beginning of the week at peak time on Malboro (around 6pm PDT?) the duty finder gets overloaded from EVERYONE farming Amdapor Keep and queuing in at like 70min wait times causing the instance servers to become entirely full.
I'm absolutely fine during the day... It's just when everyone logs in and decides to spam it.
I've only noticed it at the beginning of the last two weeks. I'm unsure if this is related to ISP throttling however I'd be surprised for it to be related to this as it's not there for the entirety of the week.
I am an EU user on an NA server (Malboro).
Again, I suffer no lag and have a solid latency of around 100 which is unnoticable "lag", in actual fact I rarely suffer from any lag.
So I'm 99% sure this is down to the duty finder servers becoming overloaded with level 50 players farming Amdapor Keep for their myth tome weekly caps.
Increase your duty finder servers substantially or I'm withdrawing my 90 day sub.
