I've been playing for the last few weeks on gemini and so the merge was not such a different experience, there were just more people playing. cyssor crashed last night, that's why it was locked, Forseral was the only pop-locked cont and the other fighting was on Ceryshen.
Re the connection, I had no loss (but it was terrible back in the day) ping was higher and there were no more retards than there usually are on werner (RIP). there was talk of an invincible vanguard driving round but other than the lag associated deaths (and strange deaths to the usual suspects from werner) i saw nothing overly suspicious. plus most people were back on their mains I guess (i was).
i've not resubbed so i expect populations will take a dive as the free time ends. i still enjoyed my time back in it and may come back to it later - but the price is high when compared to other games.
