@Caesar:

So I am about to buy G40 for all my friends to play but I always wanted to use 10 side dice instead of the standard 6 side because it makes math easier to use so the point of this post is that I want to properly adjust units attack and defense according, what do you think this should be. For example, infantry attack at 1 so with a ten sides, should it be 2 or 3 attack?

Assuming 1/6 = 16.7%, 2/6 = 33.3%, etc.

One issue I see is about combined arms.

Inf A1 (16.7%) becomes A2 on D10 rounding up and A3 with combined arms bonus. (33.3% rounded down)

But Tac A3 (50%) becomes A5 on D10 but combined arms bonus should rise to A7 if rounding up to be closer to 4/6 (66.7%).

So combined arms bonus will not be the same according to different units if you want to stay close to OOB odds.

Is it your intent to keep similar odds?

For instance, you might want to get AAA closer to historical rate which seems to be 10%, hence keeping rolling 1 on D10.

@Rank:

You get some interesting wiggle room on this one. Depending upon the unit and whether you want it to be purchased more, or less. Inf attack at 2 probably regular purchase frequency, but Inf attack at 3 is better stats than before. You may find that there are many more Infantry on the board!

**This would be advantageous for increasing the purchase of some often ignored units, by bumping up the cruiser to 7 not 6.** You will probably need to play test and figure it out.

About Cruiser A3 D3 C12, on D10 it translates into A5 D5 C12.

Rising it to A6 D6 C12 may be the way to balance this unit.

Usually, there should not be any unit which get such 6/10 because 3/6 is 50% = 5 and 4/6 is 66.7% =7

That way Cruiser combat values will be unique.

And making Destroyer A3 D3 C8 will also weakened slightly DD compared to OOB 33.3% Att and def combat values.

Converting Artillery to A3 D3 C4 and MI to A2-3 D3 C4 (imply 33.3% rounded down to 3) and Tank to A5 D5 C6 may slightly get Tank to a right balance against Inf and Art.

C5 Tank were OP while C6 Tank are a bit too costly. 5.5 IPCs would have been the right cost.
