I never tested, but after reading your words it seems that block does not affect melee, right?Can anyone confirm that? Because as it is, block seems rather useless and it is better to invest in dodge or parry.
If block and dodge work towards the same attack abilities (spell and arrow) it would be better that you max one skill (dodge) rather to get a third skill to 10 percent.
20%dodge (20 out of 100 attacks miss you) is better than 10%dodge and 10% block (meaning 10 out of 100 attacks gets dodged, and the other 90 are subject to block, where you in turn avoid damage on 9 attacks, which means that you avoid approx. 19 attacks compared to 20 from pure dodge)
But maybe the dodge skill is compared to the attack skill of the attacker, and with block its not compared but a fixed percentage.
Then it might be interesting ...
Anyone knows something and wants to share?
