Thanks for the constructed reply, that's something I can work with

Seems like there was a mistake in one of the formula, which screwed up the calculations of all the critical chances.

So that indeed means that the secondary stat is at the moment still useless, too bad, cause that would have made things a bit more interesting. I any case this also proves that power is better than cunning (quite a bit), maybe in the far future (around 3k aim will have a similar crit increase as cunning in the early 300, although this will also conflict with power, so it will be a bit more complicated) a secondary stat will be viable for a build, but for now and probably for quite a while it is not.

Also adjusting the spreadsheet to show the correct values.
