I mostly play the SHIELD Simulator when I get bored and there's nothing else worthwhile playing in the game (No Lightning Rounds, PvE on refresh, shielded in PvP event, and have healthpacks to spare). This time I decided to do an early push for 2000 though since I needed the Chavez cover to champ her and save the covers I had dying on the vine. It was an excellent decision because I have played her a lot since then. She pairs very well with Gambit.
I also pushed early for Rogue since that let me unlock the SHIELD training nodes. That one cover can absolutely make a lot of difference at the right time.
Will I push early for Kraven next season? No, probably not, he doesn't interest me. But I will absolutely get that cover sooner or later, because there will be times when I have nothing better to do than to play a couple of Sim matches.
