The best piece of advice I can offer is to play all classes every week. I've been playing since day one and every week I play all classes while doing the weekly Shaxx bounties. Playing all classes gives you better insight into the strengths and weaknesses of each class and makes dying to those classes a lot less painful. Blink strike, shoulder charge, crazy warlock melee range and fusion nades are a lot easier to shrug off when you've walked a mile in those shoes. It's a lot easier to commend your opponent when you've been on both sides of the tactics they're using. Do yourself a favor and shoulder charge the crap out of people on your titan. Clutch a trials round with your Blade Dancer, melee people in the next star system with your Warlock. Play all the classes and get to know each one. You'll be a better guardian for it. Just some food for thought :)
