I agree completely! However, with manual list refreshes every 30 minutes during waking hours, along with cherrypicking - plus strategic use of the 20 revenges per day - I've been able to hit the 345 win mark so far with only a handful of losses. But, it is definitely a full-time job to take advantage of the easier defenses.
Edit: Oh, and with a lone CG Eddie defense of my own to keep my rank a little lower.
