Amdapoor Keep - Repel Issue

Time: 11PM PST
Frequency: Often
World name: Excalibur
Character name: Avery Odette
Monster name: Demon Wall
Class/Level: DRG 50
Party or solo: 4 person party
In-game time: 12 AM
Area and coordinates: Demon Wall boss in Amdapoor Keep
Steps:
1. Party is fighting Demon Wall.
2. The Demon Wall's ability "Repel" goes off before his ability bar is finished casting, knocking members off prematurely. He also would Repel members off the sides while already casting his ground voids, making Repel extremely delayed by like 5-8 seconds.
3. Party had to exit after multiple tries and this problem persisting.

I have run this dungeon many times without this issue until today. All my party members had said that this has been happening since yesterday to them as well (and it seems to affect both PS3 and PC users). It is probably bad server lag, but it would be nice to have this specific issue looked at (and to see who else is experiencing this).

This personally has never happened to me, but it happened to the other three members in my party a few days ago. I got knocked back but they did not and then after about 10 seconds they were then knocked back. It was very strange and I'd never seen it before. Repel clearly didn't 'lag' for me, but it did for my other party members. Luckily they weren't thrown off the edge. xD

This is an issue with the instance servers lagging. The maintenance will fix it.
