Unless things have dramatically changed in the past 4 hours none of this is true at all. My last char had 29 edges.
And Warriors only get 2 legacies unless given more, some have had up to eight legacys and once there was a rager with every legacy besides egnima. It was a arial dagger spec or sword spec back in the day. Forget the name though.
The idea of points is somewhat true but hours to points is not a factor at all.
In all my experiance with edges they come in this order.
IMM EXP = alot of "points"
Pk's = a good deal of "points"
Explore and other exp = some "points"
commerece and that stuff = nothing major "points"
It seems like pk wise it comes in stages with set numbers of pk's = edge points in a ladder system with the steps spaced out as you get higher and higer.
Imm exp is set with good exp = good points
other stuff is meh.
Nothing in all my chars playing some of which age dying leads me to believe that any of it has to do with char age or hours played at all.
