I'm not quite sure why, but since the server merges I've always found it more pleasing to see players from my own server, and had a tiny annoyance seeing "-Sever X" after someones name. This feeling is most likely due to the tight community each server had back in Vanilla.
Now I think the server merges were a wonderful idea to populate the world more, but I feel like they can take it a step further by consolidating the servers even more, and give these server groups a whole new name entirely. For example I play, Magtheridon, Ysondre, Anetheron, and Altar of Storms. I feel like it could create more of a tighter community if this server group was consolidated into one single new name. With new technology, I'm sure it's possible to even take this a step further and bring even more servers together, greatly decreasing the overall number of servers, though I don't know if that really would be beneficial.
I understand people have close ties to their specific server name and it could cause an uproar, but I personally think it would be an idea worth exploring. What do you guys think?
