Who to ban? *theoretically*

None, because its not hard to deal with units unless you're stupid.

I rarely have much of a problem with fighting units, so I'm good.

But I bet most people will say:
Veronica
Surtr
Reinhardt
(Or something similar)

Legendary Tiki halloween Myrrh and Surtr. Easy. As for why, well their bst speaks for itself, as well as how utterly broken they are in stat distribution. Also there are few counters to surtr and legendary tiki, with none being f2p friendly for them for the most part. Also their skills.... And how it just makes it so hard for f2p players to do anything. That and a +10 of any of them would have about 200 bst

None

I don't really want to ban units, it takes away the challenge.

If I had to though:
Legendary Tiki
Brave Lyn
Jagen (because i hate his stupid face)

Mist,
Luke,
Grey

I'm gonna make everyone happy if summoning is in.

Brave Lyn
Veronica
Surtr

Predictable units, I know. But fuck facing against these guys.

I can't narrow it down to 3. Just armors in general. Everything is catered to them, have more powerful skills, the best bsts, the next exciting unit or holiday banner is always armor. They just bug me. It would be nice to have an armor free week. No offense to armor lovers.

Veronica is the main offender, I think. That prf is just stupid mode.

Maybe B.Ephraim because that prf is also pretty stupid

Maybe L.Lucina because that assist is imba

If they were really going to ban units, though, I think it would be on rotation. Each season or two seasons, just like bonus units, certain units are banned or incur automatic score penalties or -4 to all stats and -5HP or something like that.

Gunter, Wrys, and Jagen. They are old and deserve a break.
