The current Link-System really harms 3 server namely Elona Reach, Kodash and Riverside very badly.
All three are not linked since ever and will most likely not linked till the alliance system comes live.
Maybe Drakkar Lake wil loose it' link, and one of them get this link, but this only changes a name not the situation, still 3 server are harmed by the system.
The harm is:
They are the only "Link" that cannot get new people (since month, for month), every other "Link" in EU can get new people,
even if their Link already have more people. E.g. Elona may have more player(-hours) than Desolation, but for sure it
has much less than Deso+WSR.
But that is what they have to fight against: Links with many more player(-hours), not only other single server's.
I don't know your timing for the alliance system, but I am in doubt that it comes early enough to avoid further damage on the WvW-player base (on these servers, but every person lost on any server is a loss for WvW and GW2).
Elona, Kodash and Riverside are not the Blackgate's of EU, they aren't as overstacked to dominate the links. They shrink and are now reached all three the last places in EU (all 3 in T5 now).
Elona Reach, Kodash and Riverside aren't Blackgate
Reset is the most important time of the match for all german servers, the 4hours of the match where they are able to mobilize most player, especially this week where we are fighting each other (but this more fair match only happens every 2 weeks ...), still today at 22:00 CEST (2h after reset) there is a lot of space for more player:
