This isn't really a complaint about what worlds ended up with my world, rather, the split in general. After the split, EU will have the 2 smallest DCs by miles (and i do mean by miles) if you look at the numbers, not only will this completely shatter the pvp scene of EU (which is already barely alive) but PF PVE will be severely limited off peak hours now. People will know this, and i find it likely for people to mindlessly jump ship and abandon 1 of the EU DCs if we get an unconditional free server transfer, because no one wants to play on a small DC if the alternative is within reach with no consequences.
It was inevitable for this to happen, but i feel like you're doing it too early for EU, alternatively, you'll allow the 2 EU DCs to communicate with each other as if they were still 1 DC so people don't have to choose which friends to remain with (and some being forced away from theirs for the sake of their static) and there should only be 1 feast ladder in EU.
(edit)
My main concern here is that this will be the first time SE SPLITS data centers, as far as i'm aware we started out with 6 DCs (one might argue that the chaos relocation to EU had the "split" effect for some, but it was stated everywhere that it was recommended for people living in Europe, not people living in NA, to play on that DC to begin with. I, and many others, just don't think the number of people on our DC (and NA) justifies completely splitting and breaking up the communities like this. Ideally you'd go away from using semi incompetent 2000 hardware as servers and instead looked towards better equipment that multi billion game companies use, so it wouldn't even be necessary to split the community up in such a simple-minded way to begin with, or you will allow the data centers located on the same continent to be able to communicate with each other as i stated earlier, and other people here also stated. I don't think this is unreasonable after ffxiv's funding of ff15+DLC, i think its time to put our sub money back into ffxiv again
Splitting the community up like this (assuming no plans for cross DC communication) seems like an incompetent band aid slap across the face and nothing more.
