Okay, this is getting annoy.
Before I start, let me inform everyone about who exactly I am.
I run a really small faction (11 people) in an almost abandoned region of Ithania. We are roughly an hour & half walk north of Magnanimus. There are really only two 'pvpers' in my faction, and while we have good tactics and gear we don't have the raw power that a faction like Mag has. We prefer to dig holes, build, and rp.
Keeping that in mind, Magnanimus is COMPLETELY justified in their actions, as they have worked their abilities and members to the point where they can maintain a large scale raid war against a large number of factions. Just because you do not have the same skills they do is not their fault. It is your own. Some people choose to fight, others to RP. Regardless, it is both groups responsibility to learn how to interact with each other. PvPers have to learn how to deal with factions that use RP reasons to protect themselves, and its up to RPers to learn to do the same. Grab some throw away iron gear and go get murdered laughing. Sit in a hole and ignore them, or better yet have a friendly conversation from the safety of inside a building. If you're allowing them to keep killing you, then clearly you failed to to make your faction location secure. At which point member's deaths falls upon their faction leaders and the builders.
The thing to take away from this is that anyone can make a box with no doors, windows, or other forms of entering it. If you have the capacity to do that, you have the capacity to survive a two hour raid. Its not hard. It'd take less effort than most of the posts on this thread.
