A simple google search could've cleared that up for me I guess! Just spitballin a little. I imagine at some point I'll be rolling up a tanky guardian anyway.
I was a 5-signet warrior for the entirety of my warrior existence, and it worked out great. Never had a single problem in PvE, dungeons, or sPvP.. WvW was a little hairy... Caught flack for being a noob, so changed to try my hand at "sonic boon".. I die all the time now. Cool story, bro.
