what can i do after i’ve finished all the prologue missions and oso the event? 
!
i’ve tried shield training too but it costs me health packs and the reward isnt that gd too :c
any ideas? 
Wait around for the next PvE event to come. I would suggest trying out the PvP event, but since you’re going to get attacked a lot, I wouldn’t recommend doing that until the very last hour or two of the event if you want to get decent placement prizes.
