So for Toby's "Killing on Rails" Lore challenge

The one where you need to use his ultimate to get a double kill: Would it count to simply get the first kill with your railgun or arc mine, and then get the double using your ultimate? I had someone suggest this, and if this is the case I think it actually makes the challenge much more doable. Only issue that might come about is how long it takes to charge his ultimate; and that the time-period for a double kill might expire.

This seems to be the more popular method of getting the lore.

IMO the bigger issue is your team mates will probably kill the second target before you get the discharge off

Yes, you can; though i don’t find it any easier for the exact reason you mentioned. Poor Toby… Hopefully the Devs will see fit to fix your lore and ultimate.
