Oké so, you want to get marks but you're a lazy son of a b*tch? Keep on reading:
(you need a lvl 60+ friend of the other faction)
1) Go to Nagrand|Halaa [do it VERY EARLY in the morning / VERY LATE at night if you don't want to be disturbed]
2) Tell your mate to meet you at a place (any one where you have some 'privacy' will do)
3) Start killing your mate(get him to strip all his clothes so he has less stamina & armor & ...)
4) Keep repeating this until you have the marks you need.
Only downside would be that you don't control Halaa, you really need a raid and ALOT of free time to take it over!
