a few months before COVID19 it already started. I'm saying this because COVID19 made number of active players grow. But this doesn't seem to be the root cause;
sever lagg used to be an issue of full WVW servers when zergs were battling, which was already a bad thing, but now;
server lagg on random pve maps at random times of day at random days... We experience massive lag on almost empty map instances in the morning.. In pvp which was never the case before. And wvw has become even worse.. Often a decent duel can't take place in evening hours....
