Shadow Sorcerors or O'fury's Court

[Captain Del]

I would suggest keeping decisions like this between you and the guilds in question, because putting this out in the open may essentially cause a lot of bickering on "who's better" - not to say that both guilds in question are not equally fantastic in their own way.

As Skirata suggested, try joining both of the guilds, to see which one you like the most. Hands-on experiences tend to be the best in deciding which guild is best for you.

Best of luck, mate!
