Find people like you, who get descriminated against by the power players, and make a THIRD raid. Act independant of their authority, pvp, have fun, and nurture a positive and accepting culture in your raid. If you do this enough, Fun loving players will be attracted to you, rather than the uber raid, and YOUR raid will become the raid that people prefer to be in.
No its not discrimination, its a choice that needs to be made, everyone wants in, but there is only so much space, you call them power players? they are simply the most experienced, they are the ones the rest of the pvpers chose to make the right choice to keep pvp going, that is why they lead, its not anything against a new pvper but with goddess gone, 70 being torn to shreds and 1-15 a nosser paradise, there is 1 place left to go and even though i don't play anymore i still keep up to date in the pvp forums and it is manic in 20-30 trying to place people. Making a 3rd raid is all well and good but you get people that want to pvp hardcore but can't get into the main raids, (and i was on that end as well so i understand the feeling), that see the futility of going against the opposition with pretty much no support, hence why they try and split the power players now. In this particular case it was either kick from the raid or let a 'new pvper' see canta at its worst, getting torn to bits in 1-15 gear because you are facing people who have what you have x10.
Everyone wants to have fun and have good pvp, but when you are restricted by the game mechanics someone somewhere needs to put their foot down and say 'this is the line'.
You call it discrimination, its not, its necessity. If the raid leaders don't do something then everything crumbles. So they do what their experiences tell them is best for pvp. It's all they can do. There is only so much space and right now everyone wants in, they are the 'leader' because they have shown time and time again they can organize pvp, if they couldn't nobody would join their raids, its something you need to accept, it applies to pretty much every pvp zone.
Another time before canta was quite this popular i would have agreed with making another raid to pvp for those very reasons, but the sheer mass of people, the power of pvp and the disastrous decisions Aeria has made in recent months means it just would not work. The 3rd raid would be completely annihilated.
The raid leaders can seem heartless but i used to be one, and its not easy co-ordinating pvp, while answering pms from everyone that wants in the raid, needing to tell each one individually there is no room, making the necessarily choices doesn't mean they are singling you out, it just means they need to do what they need to do.
