I would like to get some advice on what should i unlock next from the event store. I managed to get 4,867,500 exp this nightmare event. The only heroes i got left to unlock are Pandora and Jericho, no tech on my other heroes though. And i dont have neither the juggernaut or the herald, so i was thinking about these options: Unlock all the parts for the normal and elite jugger (that's 4.6KK exp), all the parts for normal and elite herald (same 4.6KK exp), or just get parts for normal jugger and herald, plus pandora and jericho (2.6KK exp) and the rest for tech, or just get a bunch of phalanx/technical.
I didn't find the right solution from the Internet.
