In my clan, we decided to start a new clan for our lower account to participate in the current cwl. In this fresh new clan, the first opponent we get a complete unnfair match w.r.t. th-level. This means we will get crushed by this opponent, while I would expect that for the first cwl search, we would be matched up against equal clans. We have the same experience when playing cwl with th-levels below th13. We get often crushed by clans that have only th13s lined up. There is no fun in playing unfair wars. I would hope that supercell would do some balancing in the match-ups in the cwl. They did a very good job in the normal cw matchmaking.
When starting a new clan, one of the issues we face is donation. The limitation of only 6 troops and the long waiting times for additional requests don't fit wirhin fhe current game play. I can truly image that new players quit the game due to this extremely long waiting times. I think it is a good idea to have a more closer look at this.
I play this game for many years and I hope for many years to come. I think it would be nice for new players to progress a bit more rapidly through the townhall levels, but also w.r.t. the clan perks.
