Think about it, if Anet actually listened to the constant bickering over free transfers and A) stealthily patched in paid transfers next build, or B) announced that free transfers would end in, say, a week’s time, then WvW would be ruined for sure. The servers aren’t even close to evenly populated, so if it was a stealth patch they would almost never be, and current WvW standings would be this way largely forever (given the disparity, low pop servers could never move up far to compete with high pop servers, taking a lot of the fight out of the dog).
If it was announced, low tier servers would empty and pack into as many top tier servers as possible because once the boatman starts charging for ferry rides, your fate is more or less sealed. This would create deathly long queues and unplayable invisible lag armies in the top tiers and absolutely no action in the lower tiers (with the result that eventually servers would be merged into medium-high pop servers if the influx of new players didn’t fill them up quickly enough).
Simply put, Anet won’t end free transfers at this point any time soon, because they can’t. They are looking at the bigger picture, as some of you need to start doing. Look beyond your week-long matches and down the road a few months to a year. Whether we “pioneers” keep at WvW or sit out the storm to see what happens in the coming months to change it, the game as a whole will inevitably see a constant influx of new players every day until likely a year from now half the population will be “new” to us. The balance won’t come this week or next week, but it will come – change is inevitable.
As for “Full” servers becoming “High” at night and accepting new transfers: this is simply a matter of efficiency. What is best, to have your servers maxed during primetime while all but a few taper off to nearly no activity during off-peak? Or to essentially eliminate off-peak by having people find a server that isn’t full during their free time to play? Sure there is such a thing as “off-peak” now, but eventually any competitive WvW server will have some decent 24 hour coverage. These “late night” transfers are vital in achieving this, as they have already greatly contributed to filling these timeslots in servers that are beginning to see real 24 hour coverage (when that server is actively participating in WvW, that is).
If there was a culprit to the current imbalance, it would be mass transfers allowed between servers that are currently matched. Too many matches saw an early victor during the first 24-48 hours and due to the frivolous nature of server hopping, anyone on the two losing servers that wanted to win that week simply jumped ship. Their incentive to keep fighting would have been much greater if the only servers they couldn’t transfer to were the two they were currently matched against. Sure some might have voluntarily switched to a “winning server” in another matchup altogether, but I am fairly certain given the actual numbers most of these occurred within their own matchups once an early lead was clear. Fewer people would voluntarily drop down a Tier to win that matchup one lousy time, when they could still be higher up than any of those servers at the end of the week by fighting for 2nd place in their current one.
Another measure that probably should have been taken (and if it is at all possible should be considered by Anet still) was to artificially lower the total population cap of all servers across the board from day 1, to perhaps -2,000 simultaneous players of that server’s actual capacity. This would force most servers to be crowded. Then, say, once most servers had an equal population (something considered “medium” by current standards), raise the limit by 500 across all servers until that mostly filled up, then 500 more, then 500 more. Essentially controlling the maximum amount of fluctuation and effectively eliminating mass exodus / bandwagoning / crowding of servers due to these high capacity servers allowing unlimited traffic between them without restrictions (being free or paid is not the only, nor the most important factor here).
TLDR: “Free Transfers” were never the real culprit, and must stay in place for awhile to come if the servers are ever to see any true balance.
