What's so bad about the Maus?

Ectar:   You can't just stick 2 tanks in an open field 500 meter apart and use that as a comparison. You'll pretty much never get an encounter like that in a game. I've never seen a med sit in front of a Maus and trade shots with it and I've never seen one solo duel as It's always a medium flanking or getting the Maus as it's fighting stuff to it's front.  If the Maus is sitting flush straight to you and doing nothing to make use if it's armour then sure you can probably brawl it. Unless it's near the end of a battle however I highly doubt you'll find any mediums putting themselves in that situation however as the Maus will likely be at the front of the enemy push and a medium thinking he can brawl heavies is usually a dead medium.
