What Wazz and BadPenny are mentioning is a bit offtopic but I would like to shine on that aspect a bit.
In FS there are 4 types of Guilds .
1. A Guild where the majority work for the guild are to a point selfless. RP is worth something, but the Guild keeps it and the leaders decide what happens with it, its not democratic and the "leadership" decides what is done with the funds.
-Such guilds see players as an cheap asset to keep the guild going and not put each players desire first.
(If I were a competent GvGer and would want to upgrade myself on my lvl and my terms, I would NOT consider such a guild)
2. A Guild where people need to contribute but everyone is profiting from it because a % goes to the guild and the leadership and the rest is divided fair and square between the GvGers. The leadership of such guilds considers GvGers more of an employee than just an asset and as such try to keep them in their guild to further that steady income.
(If I were a new GvGer and would want to learn how to GvG and on the side earn a bit of coin, this would be a guild where I would start off from)
3. A Guild that has not figured out what GvG is all about, see it as an annoyance, dont have structure, never got into looking at it as some means to contribute to the guild, or simply lack the will and manpower to GVG.
(If I were a GVGer I would take a WIIIIDEEE angle around such guilds. Even if your selflessly GvGing, no one will aknowledge it there and you will not be going forward and have a hard time winning in GvGs)
4. A Guild that specifies in GvG, theres at least 2-4 pure GvGers that do GvG all day long and like what they do. They are the driving force that maintains a healthy GvG in the guild and they usually have a GvG-Leader who manages the GVGs, have one designated "scout" to get targets, have a philosophy in GvG and usually dont take to kindly to people who screw up in a GvG in their Guild. They can be an odd bunch that gives the leader a hard time because they may get douchy at times or simply bragg all day long how great it is to be a GvGer. Thats why there are specially GvG guilds who take them in, at a point where they will need to be self sufficient and know their trade, the payment will go up accordingly, usually 100% is used for the GvGers themselves and their GvG leader and earnings are not deducted to a third source, Guild expenses excluded.
(If I were a competent GvGer who knows my trade, that would be the guild where I would be happy in since the people there would have the same mindset. But it has alot to do with the leader aswell. If the leader cant lead. GvG guilds will wayne and fail.)
