So guilds that chose to uo their roster to 50 will not be able to participate in the alliance system in terms of point sharing ? Then will bigger guilds not have the option to have allies completely? If so that could be disadvantageous for big guilds as maintaining a 50 player guild active and organised will be much more difficult than two seperate guilds teaming up as organising those will be easier giving them the upper hand?
Just a though obviously no one knows how it will play out until it's implemented but guilds might chose just having two leaders and two tags instead of a big guild anyways ?
