Lag when killing mobs at boss maps

One-shotting a large amount of mobs on a boss map will produce a large amount of lag.

Mainly happens at Zakum, Chaos Zakum, and Empress Scrubby Garden. Probably doesn't happen that much at HT.



I also tried killing the Scrubby Garden mobs one at a time and dc'd from that yesterday and today. And too many there will dc you upon entry so avoiding them isn't a good solution.

Does anyone have any good ways around this?

I've experienced this at HT when wyverns or cornians are summoned mid spam of blade burst while I'm attacking tail arms and wings. I haven't found any way around it either in fact it's caused me a few deaths at HT because of it.

I'm now having lag problems on non-boss maps too as of the v128 patch. Went to ToT and got crazy lag whenever I killed stuff.
