Nothing as you don't lose combat bonds when you die. This, I imagine, is quite a large reason behind the timeframe.
The question was how to track them, and it still stands.
Yes that is correct.
I was running a Krait with 2 torps and 3 Enhanced AX Multicannons (class 3). I was with one other person, we picked a vent next to each other, I went left they went right so we got them all. I was getting 400,000+ bond per attack on the core. Sometimes up to 700k.
So you'd only need to do 3-5 runs to hit the 2 mill, and that can be done at any point within a week before it enters meltdown.
This brings up another interesting question (that may have been asked already but I didn't see). Do the 2 million credits have to be earned in the same week the titan is destroyed, or can they be earned at any time, but the last time the core was damaged by the player has to be within a week of destruction?
And for that matter, is it a rolling week, or per weekly server restart?
I know it seems like I'm nitpicking the new rules, but I fully expect people to fall into these edge cases and fail to receive any rewards, and I just think the rules should be made crystal clear before that happens.
