Hey bro, try some Court of Orxy. If you get in there with a big group (doesn't have to be your fireteam, randos will do just fine), stay for a while, pop a few runes if you have them, and kill as many bosses as you can. You'll get mediocre rewards for other people's runes, and better rewards for your runes, hence why I said use some if you have them. But... regardless, you will walk away with full character gear slots, and a plethora of engrams on the ground, being warp driven to your postmaster. I always tend to walk away with at least one blue over 290. Might land a 297 blue sniper or a 295 blue AR. As for your heavy, that's going to be the rarest. I have been lucky enough to receive one blue heavy at 299 (now my Ruin Wake is a 299 monster), and I've received a 297 blue heavy, as well as a couple 292/293's. They are rare, but they will eventually come. But like I said, sometimes the court is the better choice. More engrams than strikes, in less the time. Hope this helps, and good luck. Once you hit 300, and start getting the occasional 310 exotics, you'll jump up a few more levels rather quickly, by equipping your best 310 exotics and using the other ones to infuse into your best, highest legendary gear. Then, all you can do is raid to continue progressing. For now, at least.
