Different clans offer different styles of learning, each with their own merits.
- Training clans like Outlaws, GGr and 101st seem to focus the most on a game analysis method of self improvement where collectively the clan uses its best players to teach their lower players. As far as I can tell, this is more independent approach then a clan wide approach. It requires intiative on the part of players to be engaged.
- Larger clans like FCC, Hydra and CORP have a more unstructured approach where the clan offers large clan-run leagues for activity and to get people playing each other. This approach is less hands on but one-on-one games and tutoring can still happen although it isn't a priority for the clan's management.
All these clans offer community, but the way you want to engage with them is different. Hydra and 101st/Lynx use Discord. FCC, Outlaws, Apprentice/Masters use Skype. CORP uses a game chat and clan forums. I don't know about GG/GGr but I would guess skype or game chat.
The main advantage to Discord is a more structured approach to chatting with a clan server having multiple channels with topics so you can more easily follow along on relevant topics. Skype has an unstructured approach where, depending on the chat's activity, you can have hundreds or thousands of messages each day to go through meaning you miss things that might have been relevant. But Skype still is where the majority of active warlighters are. People tend to use Discord and Skype or just Skype. Its a one-way street unfortunately. But that's my little explanation of the chat situation on warlight.
Lastly, to the question of making a new account, I don't know if it really matters to make a new account. If the point is you are going to be active on warlight and not get booted anymore, then why make a new account? Its not like your boot rate will be reflective anymore of how you play. Unless you play a lot of open games, your boot rate wont come up much.
