I don't Play a warrior or a darknigth so i might miss Infos about them to compare Paladin with them

BUT:
I don't see any threat issue for Paladin and i've run with players wearing gear roughly 20 ilvl above mine.
the only time i could actually get into Trouble with thread is when i get to cought up with my new toys and miss out on threat generation but that would be my own fault.
