I would really like to see Heroes Trials get a sweeps option.
The fast forward option is great, really. I run Heroes Trial far more now than I ever did before, just due to that option.
But having to swap bases and change heroes around to ensure a win can get old really fast, especially during GW, where the new design and heroes might be terrible on defense and cost you points.
Now I get that there are many different heroes that could pop out, which is probably why it doesn't have that already, but I think there is a simple way to keep that in mind and still allow sweeping.
Keeping track of which heroes they've defeated out of a Heroes Trial set should be a fairly easy and minor change. Then once someone has defeated every Hero that can come out from a given set, it allows sweeping of that set from then on.
So once you've beaten every Hero that could possibly come out from HT L12, you can then sweep L12 instead of having to actually run it.
That way you have a challenge to pass, but once you do you get a nice reward in the form of sweeping them, if you so choose.
Move along, please.
