Disagree. Then how would the top guilds ever be beaten? As you've noticed the game isnt quite accurate with how it pairs up wars and to stand a chance the weaker guilds are forced to use MB to atleast try for the tie. Implement that tie breaker and watch how much interest is lost in wars as the weaker guilds would rather not even attempt entering wars knowing that basically 50% or more of the time they will never stand a chance at even tieing it up. You'll be faced with a monopoly the stronger guilds will have over wars and a why even bother attitude the weaker guilds will adopt.
Surely you beat people by playing the game better and developing better strats (both individual teams strategies, as well as guild-wide strategies on how you approach the challenge as a group), rather than just throwing money at the issue!?
In our last GvG one of our teams, who was lvl15 beat 3 lvl24 sides without using MB - shows it's possible to beat higher rated teams with brain rather than bank.
You have a pretty low opinion of people if you think people play this game, so as not to play!!! Of course people will still want to have a go and test themselves against other teams in other guilds! Also, you'll have just as much of a chance of being drawn against a weaker guild as you would being drawn against a stronger one - so it should be relatively fair.
