Can't really disagree with anything there. Members and ranks being involved in both scenes has definitely proven sour for the progress of the pure scene. This is particular with multiclanning (rev alliance) and members being poached from the pure clans involved (rot alliance). The scene gets a little smaller each time this issue peaks, as it has been a lingering issue since the beginning if 2020.
At the end of the day, pure clans are being used as proxies for main clan beef so that no main clans need to take an official loss. Rage get smoked? Rev don't lose for propaganda purposes. Zenith/Apex get smoked? Rot don't lose for propaganda purposes. With this whole ordeal, pure clans lose out 100% of the time. In an ideal situation, yes multiclanning should be minimised, or non existant between the scenes if main clans are going to be anal about it.
The ego issue is purely based on rivalries. The rage sided clans will all have clean action with eachother. The zenith sided clans will all have clean action with eachother. Due to not wanting to lose or wanting to grief their rivals with mains and 1 item rag (the no action for 'x' clan mentality), clans crashing aren't trying to form a cluster, they're trying to ruin their rival's action and turn it into the tine consuming ns wars at a 1 click return spot.
And as @nawepointed out, avoider mentality is crazy right now. Clans that historically prepped everybody and competed for top matched spots now spend their time avoiding most clans. At the very least, more clans should be fighting regardless of their rivalries. Preps are perfect ego fuellers, they should be gunning for the clan wars wins as well over their rivals (but not go for a 1 and done if they win).
One last note, a 1 Defence reset won't change all these cancerous mentalities, but it would be a very nice direction for the health of the scene and bringing in new blood. Generally, more seasoned clanners are the ones fine with defence. If we want lots of new blood, allowing a 1 Defence norm will advertise the scene very well.
Edit: sorry, one more thing. Clans should stop wearing team capes on weekends IMO because it enables mains to be very actively involved. Clan cloaks won't stop it, but it'll stop a lot of the cancer and effectiveness of multi logs and click rag on weekends. Supremacy and Fo do this well, and from an observant point of view they don't seem to be involved with bringing mains personally.
