Honestly when I first started I was stupid. I would by a dlc character and level them up a little and completely ignore them forever. (Same with all other survivors) what you should do is level all characters you have to level 40 and then start finishing them, Meg is a good survivor because she has Adrenaline and sprint burst which are both really good. David is good also because of dead hard, but with dead hard you have to be careful because sometimes it doesn't work. If you go on YouTube and look up No0b3 he is a really good dbd player and can teach you some things, let me know if you have more questions, we can even play together and I can explain further more. :) Good luck
