when I started playing almost 6 years ago, we lost a lot of players due to the lag that spoiled the game play. We have come down the road 6 years later, and we back to one zone blob on our home bl's, which seems the modus operandi for most servers. The zone blobs are causing huge lag again, and I would like to suggest that if zone blobs persist, that the number of players trying to enter a map are choked for a time period to restrict the skill lag. I have suggested before that if a group of more than 20 players in a group are within 10,000 feet of each other, then maybe vulnerability to the whole squad will cause squads to be smaller.
The positive side to the linking, is their is more activity in WvW, and it fulfils the current need, its just 6 years later we gone round the same mountain and I have seen many suggestions, but nothing to deal with the inherent problem of a full zone blob.
