Yes, it’s definitely worth it! I roam WvW on EU server from Brisbane - average ping around 380 (using WTFast). And I don’t completely suck. Play a ranged class and keep your distance as much as you can. NA server ping is definitely better tho.
When these restructuring changes take place, perhaps guilds could have the option to change their name? A lot of guild names are relevant to the server they’re currently on, which will no longer exist.
