It pulls stats from my.lotro.com and it only compares your toon with others that are currently on the server, so any stats that might have been affected by food or cappy buffs will also be recorded at the time the data was captured. With that said...
Since most of the time I'm Spear/ Assailment traited (melee/ ranged DPS), my Morale is below the server average (11559/ 13192.4638), but my Might (1227/ 799.7007) is well above the server average. I'm banking this on most of Dwarrowdelf Wardens being sub-lvl 75, or just reaching lvl 75. And, when tanking, my Morale (with pure Vitality jewelry on and hardly any Might gear equipped), my Morale can max out at 21,005 (I'm not claiming that it was my max morale that this particular data cap has recorded, but I am saying that I have reached this morale threshold more than a few times).
I think, however, that the highest Might recorded for Wardens might be Shaera of Reforged, if I'm not mistaken. That girl's raid crazy! Wish I could be as diligent as her when it comes to getting gear, I'd very much like my Might and Agility to be higher.
