I like my dex
I mean when I fight in the catacombs, I block about 1/4 of the time, id like if it was higher
But I trust u, so I won't
Blocking is good, but at one point, the
skill becomes less effective. For example, the difference between level 80 and 100 dex is minimal. 20 points in another skill can make a
BIG differance.
A tank is meant for taking the damage or keeping the aggression of a boss or harder mob. For bosses, im not 100% sure, but I don't think you can dodge. Vitality is far more important in a boss fight. If you can dodge during a boss fight, then 40 dex is fine because if you put any more, you will leave your vitality lower than it should be.
Your probably wondering then, "Why put any dex if it's useless for bosses?". Here is why its okay to put dex. There are quest mobs that act as bosses, but are not (You can dodge/block). Also, like you said, you block quite a bit while training. This can be useful.
