You guys should really, for the second time, change the name.
1. Yes, it was an EU Clan but I'm sure the proper Legends don't want another division without their permission.
2. They created the clan/name first, therefore if they return they will be using that name. And if they do, you basically copied them.
Either way, no offence (I'm not into AU), but from what I've seen, you've made a ton of clans which haven't lasted, Legends don't want people to search for them then find this. There are a lot of details which I have excluded for the sake of flaming.
Overall, Legends will keep coming down on your thread like a ton of bricks, so I suggest you change the name, before higher consequences
