My vote = No. Leave things as is. This is opening a can of worms, people will want doubler to count for titans, hunting LE or chompers for drops, heck I could even argue it should apply for pvp hits. See the trend?
+1 I totally agree. It should be left the way it is. Doubler should be used for increasing EXP and Gold gain only, not for doubling kills. This just seems to be a lazy way of getting things done quicker. What ever happened to No Pain No Gain??? So I vote NO
