This is kind of the drum I’m beating. It’s dumb that GoW’s only message is, “Don’t start new guilds. Join the ones that are already up there. They mysteriously shed 2-3 players every week, you’ll get in!”
It also means those guilds at the top don’t often face new challengers, as there’s dozens if not hundreds of brackets of buffer between them and talented new players. So it’s most likely those talented players go join them until they burn out instead of making a new guild that challenges the top guilds. Then they leave and get replaced again by the next person disgruntled with the climb, etc. The end result is the “best guilds” are comfy, sure in the knowledge they will only have to face the same guilds over and over again and won’t ever lose many of their rewards. It’s not that it isn’t hard to maintain that position, but they never have to face the risk of there being a new, innovative challenger from the outside. (A lot of the troop design prevents that too, it’s not just the ladder.)
There’s not a “the problem”. There are a lot of systems interacting and the whole thing sort of stinks. GW and its bracket system made sense when GoW was small and GW was the only competitive event. It is set up for a small game and GoW is not a small game anymore. The only people who benefit from the current system are the guilds in the top brackets. They “earned” those positions for the most part 3+ years ago, and now that it’s monthly it’s even less likely anyone will ever beat them.
So of course you defend it. You benefit very much from having your seat reserved, and you know even if you lose it there’s a nice one next to it you’ll get. It’d be a shame if you had to think about defending your seat more than once per month and the consequences of losing it existed, wouldn’t it?
