GW2 doesn't have builds like GW1 has. It has preloaded skill sets depending on what weapon you're using. Hardly any flexibility at all. So there are plenty of reasons not to play GW2, but fear of being ridiculed for being a special flower should not be one of them.
That said, keep playing how you like. The only no-no skill to bring is any resurrection spell (other than res signet).
I've played a lot of RA, it's where I've done most of my pvp. I used some unconventional, sometimes experimental builds, and when they work, they work well. When they don't, they don't. It's why you're on a team, and why it's called random.
Keep at it, and good luck to you!
