This is 95% probable.
As of Wednesday the 18th, Enigma will be joining Twelve. This is due to a variety of reasons, however mainly due to the fact we don't have a large enough core group of members to sustain the guild for 25 man raids.
Anyone is welcome to stay in Enigma or look for another guild, however all active members will be allowed invites into Twelve. You can pst Myra for an invite on Wednesday the 18th or later.
We will be maintaining our own Karazhan group, and this will work alongside with the 2 Twelve Karazhan groups. THis means for our own Kara core members nothing will change, and for those who are spares in Kara it might be possible to form a fourth Kara group with Twelve spares, or at least you have 3 raids you can fill in for rather than one.
1 or more Enigma members will be involved in Twelve officer decisions, however we must remember since we are joining Twelve their curret 25man raiders will be given prioirty at least until people prove themselves.
I have thought hard about the decision, but I believe the positives outweigh the negatives, and at the very least we will probably be in no worse a position at Twelve than we are at now.
Don't forget we have raided sucessfully with Twelve in the past, and this should be no different to Nax, except on a permament basis.
If anyone has any questions please let me know.
