Cut your emotional investment in this game.

Stop the ME3MP nostalgia and let's be honest. This "multiplayer" is not only a trainwreck of massive proportions; the efforts put forward by its talented dev team in attempts to salvage it have been so far laughable. While you're probably in denial right now, investing time and effort grinding this utter mess of a game hoping that things will get better in a year or two, just take a look back at DAI:MP. Same team lead who loves to keep things "corporate", keep the creative talent under a leash/budget, be extremely passive towards any sort of criticism and towards actually fixing the game, and have zero standards when it comes to quality content and control; the only reason it got any better was due to Luke B. pouring his heart into the game trying to salvage it out of love. (the man created half of the Dragonslayer DLC content then 5 months worth of content including 2 new difficulties, weekly balance, etc). And yet he only could achieve so much as he was kept under a leash.

"But the game has only been out for 3 weeks", yeah what a bunch of bs. If the devs themselves had any sort of emotional investment in their own game (i.e actually play it instead of streaming Destiny every day instead), maybe they'd put out weekly balance patches and, maybe if they were to release weekly events (such as the boss event last week), actually do some TESTING beforehand to make sure the stuff works instead of looking like absolute idiots on stream. Yeah, you know why none of that is happening? Because they, themselves, don't give a fuck.

I could rant on for much longer but here's the point: if you're not enjoying what you're playing right now, I'd suggest you to stop, and maybe come back in ... never, because it won't get better.
