I am an experienced raider that takes criticism well

A little about me IRL. I am an 'old' guy....43. Retired Army and I work for a general contracting company. I do some volunteering especially with severely wounded veterans.
I am looking for a guild that is mature and laid-back, where I can hopefully make some longtime online friends. I like raid progression like anyone else, but I also like community and cameraderie.
I am currently playing an Engineer Tank, and plan on being an architect.
