Dominant Species Challenge
I am currently working on beating all of the Borderlands challenges. I have most of them completed and the rest I have found efficient ways to beat. However, Dominant Species (kill 2500 Guardians) is taking forever and a day. My method has been so far to go through The Descent and Eridian Promontory and just keep killing them. This method is taking ages as I have been doing it on and off for months and am getting serious again about finishing this challenge, but I am only at 1000. So my question is: Is there a more efficient way of completing this challenge?? This is just taking forever and would like some insight on whether my current method is efficient or there could be faster ways of killing guardians. Also, I noticed that certain types of guardians don't count for the total. Why is that? Thanks.
