Starting off with some sensible assumptions:
1. Most people in Cyrodiil are in large groups (4-12 members) or faction stacked.
2. In primetime (or pretty much all the time now with the current game performance), <50% of skills actually register on time*.
3. In lag, groups/zergs can still get enough skills off for burst/survival while solos/duos can't.
4. Solos/duos can't afford to "build for lag" ie more hp/sustain as it is already so hard to kill in the current tank/heal meta, but group players can.
*Just my experience playing from Australia. I don't know if it's actually that bad for everyone else.
So that got me thinking about these groups that get absolutely dumpstered Xv2 during lag free times, but transform into unkillable gods during lag. Do they actually enjoy lag because it lets them survive longer? And due to their advantage in lag, they've stayed on and formed the majority of the remaining population in Cyrodiil? I've barely seen any 1vXers on and even when I see skilled players, they're not as successful as they were before. Is the natural consequence of bad Cyrodiil performance just faction stacks vs doors / low pop to take advantage of the lag created?
