In regards to undermanning, if you take the risk you can get rewarded with extra banners. If you don’t you won’t get extra banners. Take Geonosians as an example. It’s an easy team to under-man by using Darth Vader and possible a second character like Thrawn. Can you run a full team to positively nuke them? Sure, same as you being able to just take those 2 and doing the same. Then there are teams where under-manning is a ridiculous proposition, like if someone places JMK w CAT on defense.
As for the argument of running a full team to get a guaranteed win or running -1 person, like the CLS v JKR fight mentioned earlier, I don’t get why you’d want to underman a team you only have a chance at beating down one character. If you lose congrats you just lost CLS’ team, which realistically should be used elsewhere.
“Let’s stay on subject to this post” can be applied to any post made on the forums. Tagging the devs in a lot of your posts doesn’t mean you can magically summon them. So yes this is on topic since it’s being posted here…
