I’m trying to come up with a reply better than just “No!”
This would be a big change in roster building and strategy, lead to a greater spend of hp, and limit diversity of characters played. Can you imagine the uproar?!
In addition this such a huge change would have to be coded, tested, and would inevitably suffer from bugs (and take resources from fixing currently known bugs).
TL;DR: Not just no, but tinygoldfishing tinypuppy no!
in my most recent simulator clear I used 6 different teams on those nodes and at least 15 different characters. I loved it and I think that is what the devs would like to see - different team compositions. this seems like it would severely limit those options and work against the stated goals of the devs.
