The point that matters here is that people from outside Europe should be expecting to be somewhat laggy - if only by distance latency - to this server.
Having this knowledge, but despite of that entering queues for PvP and PvE already qualifies as griefplay for me, because they know of their distance problem or even spikes and enter any content regardless of anyone's time they could ruin.
Same goes for people inside Europe who are lagging and spiking badly by the way. If you know you are lagging, just dont que. If you knowingly force a bad time on anyone who comes into contact with you, you're a douche.
And I'm talking from a gameplay perspective here too.
If we look at what lags might cause:
- delay lag-sensitive skills, such as Shadow Bolt, Evoke, Blood Cutter
- delay or stop monsters from taking damage properly
- glitch out the natural location of monsters and their attacks
- glitch out movement patterns of monsters
- glitch out spawning locations
> prevents proper on-point playstyles, which can be annoying and infuriating in endgame dungeons. Not even to talk about PvP here, where combos won't work properly at all, especially if chosing a class that is very susceptible to lag spikes.
