I'm glad I'm not the only one who has noticed. Thought I was crazy... and you're right, it does take away some of the enjoyment and replace it with frustration.
Guess I'll just keep battling through and see if things improve.
Maybe I'm just a conspiracy nut, but I'm wondering if as my level increases and the availability of higher level clubs becomes available if that offsets the difficulty somewhat. From a programmer's/business model standpoint that would make sense -- offset the increasing difficulty with new clubs. Keep the cash flowing.
Time will tell.
