Sounds like skill issue to be honest - if you farm well and deny you don't fall far behind even if you eat dirt during the laning phase. Even if you get absolutely stomped and denied, there are still a lot of chances for you to return into the game by catching waves and pushing them out and jungling.
I'm kinda mid-to-high MMR right now (to the point where I can't really play together with friends as we get always separated), and I've had so many games where I went 0/5 in the laning phase with a soul deficit, then ended up jungling/pushing waves/jumping on enemies if they were alone and then suddenly being top or close to top in souls on my team.
I have prior MOBA experience and played Deadlock for around 50 hours already, and it's a good game IMO. Of course, it's not perfect and I do have a couple issues with it but it kinda deserves the hype.
