Horrid Lag at LHC!

Moment ago I was in 6 person Lionheart Castle party and the lag was...insane. I kept getting spikes like every 3-5secs.

Is it just me or is anyone else having it too? And what would be the tips for reducing it?

Do you lag in large boss fights? Then you'll lag here. Get a better comp.

If you don't lag in large boss fights then it's probably something on Nexon's end that you can't do anything about.

4 hours of LHC with 2 full parties in the map. No lag at all.
