Not 100, but since EC's no longer drop from em, it wouldn't hurt to up it to maybe 40.
you could also drag alts along as you farm once you have your max opened on one char pick them up with the other character, set the squad onto free mode
I think opening unlimited chests should be possible.
Making it 80 would be pointless. I say just make it to where we can open 100.
I said up it TO 40, not up it by 40. If I remember correctly, you can open 30 right now. That limit was there to not kill the economy further.
