Hello, been playing for a little while, at lvl 300ish and what seems to be very apparent at higher lvls (but prior to getting all cities to 5 stars). Only a small subset of troops are good at leading your team.
Attack stats are high enough that most troops are 3 skull matches from being eaten. This isn’t the end of the world per say but those with stone-skin as so much better than other leads. Of those with this trait there are really only:
Of these Emperor is so so much better than the others, once you get him you will never use the others (except maybe Treant)
With just a small change you can add a huge number of troops to the lead position and create all kinds of interesting team creations.
All you need to do is this:
Armored: Reduce ALL damage dealt to the troop by 25%
Regeneration: Regenerate 2 life each turn.
These two changes would make so many more troops viable as leads, especially the first one. There are a number of situations where armored might even be better than stone-skin against some teams. And yet it wouldn’t be op.

All of these would be real choices in both defense and offense
You might even consider these for real as well.
