Hello, I am writing this guide to any new players that end up seeing this. The current guide is outdated so this could potntially serve as a new one. Hope this helps, and enables you to not make any stupid mistakes on the way.
1. Starting out: Do's and don'ts
2. Level 1-10: Get some grinder marauders
3. Level 11-30: Get sea wolves.
4. Level 31-50: Get Punishers and start FM.
Each section will be its own post. Don't be afraid to ask questions though.
