Difficulty of enemies is keyed on your xp progress in A17 it seems ( please correct me if I'm wrong). I don't see rushing xp gain is making you better because you will be at a high level with difficult enemies but don't have the good gear and materials to defend yourself.A new player if going solo, needs to play on the easiest settings and 120 mins per day
and shortest night
and airdrops every day.
Might have a chance if they don't want to die a lot.
Multi-player (even 2) is much stronger.
Edit: Why Multi-player is far better:
Group up and don't stop killing zombies for the first 4 days, for a big boost to exp, as each player will have a multiple that a single play could get. (I.E. with the shared experience, 4 players could each have 4 times the exp).
This strategy worked much better in A16 because there enemy difficulty increased constantly with time so getting xp fast gave you an advantage
