1) Do not join an Open Clan under any circumstances. 2) Do not join a clan created after January 31, 2021, under any circumstances. 3) If the clan chat is full of Idle requests and Clan Wars updates, run away, run fast, run far, and never look back.
And the 3 tips:
#1 - If you are interested in competitive strategic Warlight and looking to improve, join Discovery, M'Hunters, or 101st. #2 - If you are interested in competitive strategic Warlight and already good, join a clan that will be in Division A next season of Clan League. #3 - If you are not interested in competitive strategic Warlight, you are playing the game wrong.
A little more tips: 1. If you are interested in hardcore competitive warzone, look at the CL spreadsheet. Depending on your ego or win rate, join ones in that divisions. 2. If you are interested in casual competitive warzone, look at the CW8 placements. Should be the higher the better, but you can also join ones that perform in CW better than CL. 3. If you are not interested in competitive warzone, just join your closest friend's clan, or create one using... money.
