Well, I think I finally found the key to Detonator lol. Finished the campaign getting all elite golds except in detonator. Sat down today and tried the detonator event in the second grid (was able to get the elite gold in the first grid), which was on Talons Junction. The target was 320,000. My first attempt fell short of my best of 250,000. My second attempt was 251,000. Then it all just clicked and I scored 520,000 or so on my 3rd attempt, which, according to the global rankings, was good for 11th in the world. I know there have been problems with the rankings, so I doubt that's accurate though. Anyway, I'm just excited to have figured it out and hopefully now I can blow through the rest of them on elite, so I can stop looking at those plain old novice golds lol.
