I can understand that you need a simple system for TT, without overly complicated calculations, and for this the DnD system is remarkably differentiating. There are some big mistakes still. Now, on a digital game, some faults could be dealt with, instead Larian sadly made it worse.
But I think some of my thoughts would not be for many. I would give more abilities to some weapons, so all have pros and cons. I would also say f.e. that AC from a shield should only count when it is out, and that changing a weapon set at least costs a bonus action.
...
My only big complaint is that a great axe should be 2d6, like the greatsword and maul, there's no reason for it not to be, and the only reason I can come up with as to why its a d12 is that it's the typical barbarian weapon, and barbarians are already using a d12, and the d12 is one of the lesser used dice.
Here I would like to differ. I think it is ok to have some variants. A 2d6 may sound better generally, but a 1d12 could be better for criticals. So you have more options for your playstyle if the weapons have different dices. I would really like it if there would be more such options, f.e. slings doing 1d4 but allowing a bonus action, or a chance to apply prone. Even better perhaps to have f.e. twohanders with 2d6 and 1d12, for visual preferences.
