I've always been willing to try new builds for my alt, yet I don't know a lot of things about my char : namely what are the penalties from PD/PT on my wpf, what agi actually does, what's the (updated) penalty of armor, the effects of ironflesh on said armor, the penalty-free weight limit, and how it works with the armor penalty multipliers. The only calculator I've been able to download is Poul's, yet it's 3 years old, and while it still allows me to plan builds, it mentions none of what I said above, which are game changers.
So, basically, did anyone make/update a calculator I didn't hear of while I was gone ? Or are there plans for the devs to make a calculator on the website itself, or to explain stuff better than it currently does ?
