Yeah doing an average based on how much estimated damage is going to be done summed up as 75% is a bit of a hokey way, but unfortunately, that would be the only 'approximation' of damage dealt that we have atm I guess.
What I would say is, creatures are like n00bs, they make as little as quarter damage no matter what mob they are. How often they do that and how often they miss is to do with the calculations made against the avatar's Agility and Defence profession against the Mobs Intel and Strength values. (This is what I feel is going on, although I've no conclusive proof of this)
For information, with my level of Evade (Level 30 Evader and 71.3 Agility), Atrox Gaurdian makes mainly 50% or less sized hits with occasional streaks of 75+ dmg (un-armored.) I know this because I was doing them naked last night
Needless to say, I'm still not quite good enough to do Atrox Gaurdian+ naked for any sustainable amount of time with a FAP-90
But that's off going off topic
Anyhow, I'll say it again, good work for getting that on there Witte. It's a real handy addition to the MobLevel chart.
Can I ask for a tweak to be made to the weights column in the Armour so that a weight shows up as green if all figures are entered and red if one or more figures are missing. Save people having to go into each armour set and check the weight is entered on each part. It's not a priority change, just a nice to have I guess.
