I had a couple more thoughts on the flexibility of the "2 dice limit" on weapons that wizards have in T&T.
First, there are certainly more weapons in the world than those listed in the 5th and 7th edition rulebooks. A game master or even a player could find other historical weapons and give them T&T attributes. There are many examples of this posted by other players on the Trollbridge and published by Flying Buffalo within the pages of Sorcerer's Apprentice, various solo adventures, and GM adventures. What is great about this for the topic of wizard's weapons is that if the new weapons only have 2 dice, then a wizard could use them regardless of the type of weapon. So, there is always the potential for more weapons in the wizards arsenal.
Second, there is the possibility of crafting "special" weapons for wizards that they may not otherwise be able to use. Weapons can be enchanted to have special abilities, would it not be possible to have an enchanted broadsword that only gets 2 dice? "A 2 dice broadsword," you ask, "what use is that?" Remember that the restriction only applied to dice and not to weapon adds. That enchanted broadsword might therefore have 15 adds. So now you have a wizard wielding a broadsword that gets 2D+15. Not too bad.
Ok, on to new topics.
