I'll chip in. So a few months back I made this clip as there was a night & day difference in my performance in a single clash, no extreme number of players involved and not too many effects. so i dove into the details and noticed that soon as the MSH Cooldown increaser hit me that was when my game started to stutter like crazy, and 08 sec into the clip as the effect faded off my game regained its performance. (granted i had more addons running back then such as WSCT and that addon is killing performance too)

An other eksample of the "inc lag" when your game starts loading abig ammount of players in a direction, usually when you enter a keep and theres 100s of players inside you feel the "load". In this case it was me turning around to a 1-3warband "inc lag" making the lag so bad i ran into a lamppost lol:

a 3rd sitution where I got some crazy frame drops to the extend where i lose control of my own manuvers and run into the bridge wall because the game is so choppy:

I have a pretty new and beast computer, able to play modern MMOs such as Black Desert online and do 50v50 battlegrounds on highest settings with no lag. But this game i feel i cant even have effects on because of these lagbombs you encounter in largescale, from different reasons it seems. Now without calling it worse or better on one realm, I have however heard several guilds who have played both sides state that playing on Order and facing destro, is notisable worse.
