You can't be serious. If the character is used for dps, of course I take 2 strength over 20 endurance.
Why would I ever want something as useless as endurance for a dps toon when endurance does not affect the damage I do at all?
If the stat changes were -2 strength and +20 endurance, then that would mean less dps.
The only time the endurance would have any use for would be either in pvp or or strictly solo-playing in pve, but if I had any intention of using the character for PvE group content, then I would take any amount of main stat, no matter how small, over any amount of endurance, no matter how high.
I'm neither seroius nor not serious, I was just asking, got that?
