ive recently started playing factions, which I love. however I've noticed how much the lag effects the game. this same lag isn't present on sky block, I can't say for other games. the lag on factions can be annoying, it makes opening crates slower, exits you from chests right when you open it, and disconnects me when I'm "capping the KOTH" thus making me start over. I don't know if anything can be done about lag but if something can be done that would be totally rad.
Not to mention all the glitches in this gamemode, however its being reset soon so I think you should just wait for the reset.
