Attribute/Stat Caps?
I don’t think so, but I think there is just a real limit to how far you can make a stat go.
“At this time, Power also has a cap that increases per level, effectively making sure that two opponents of the same level have an equal chance to win.” – http://wiki.guildwars2.com/wiki/Power
However, there is no further information on what this “cap” is or how it’s calculated. I’m with Joey.3928, with “max stat” armor, there is only so far you can go anyway and a lower cap just seems mean.
