They usually keep number of players to max 10k players altho the number can go much higher if needed.
Now, can EVE server do the same? No.
Max that i saw in one instance was 12k players in Jita way back when. And I remember the lag was noticeable(or how they would call it “time dilution”).
On one instance, usually, eve has up to 50 players. Mostly less then 10, even 5.
But again- you think WHOLE EVE UNIVERSE is one single server. And that is just not true.
Like you said- just because YOU want it to be true…and such.
About you having “great time” and “never had any problems”, LITERALLY ONE LOOK AT YOUR PROFILE, brought me to this:
Are you certain that you have ANY knowledge about what you are talking about?
Are you sure?
AGAIN, DO NOT defend this game, CCP do not know nor care that you exist.
