I disagree, the RIGHT cheapies can get the job done and that leaves you more money to spend on your hitting.
Like I said earlier, two possible philosophies: OUTSLUG everyone or have a somewhat balanced team. There is nothing in between IMHO.
I have won 4 or 5 of my rings on outright bomber teams, simply pummelling the other team to death. It can and does work if you have the right players.
