Bro... My original account got permabanned on Xbox live. The gametag is LOG HeadHunterX if you wanna look that up, but that's not the point here. I got this account which was my backup from 280 light to 370 in about 2 weeks then I got to 385 after about a month and I'm 392 now. I'm just saying no it's really not hard to level up in destiny as long as you're putting yourself in the right situation to do so. If you can't do iron banner, trials, and raiding then yea you're going to struggle. If you can do all endgame content in this game though you're not going to have issues leveling up.
