As is, the sweet spot for TSB is silver. In silver, resources can be farmed and bonus players can be maxed out without much thought. At gold(and beyond), resources become a huge burden and must be carefully considered. As a whole, the club events are much easier in the lower levels than their more 'advanced' counterparts. I'm currently in silver and although I'd love the idea of moving forward to gold, there's absolutely no incentive to do so.
I propose that higher level(silver/gold/plat/diamond) should get multipliers for club events. This would encourage teams to move up and give us some much needed variety. It would also add a nice layer of strategy when forming clubs.
If you're not having fun, you're losing.
