I ran a couple of mini-gaming sessions with my daughter.
She ran a combat orientated character with 3 CAs.
A sort of barbarian character with light armor, dual weapons and a bow.
I NPC'd a character with 2 CAs a Sword+shield combo and a bow and Hard leather armor.
Sort of an ex town guard type character,
I did a small adventure where a small town's windmill was inhabited by some sort of ghost (actually harpies pretending to be poltergeists)
The Barbarian didn't have much in the way of any social skills and a fairly low CHA and not a high DEX, average INT. Enough to get him 3 CAs.
He did have decent survival and outdoor skills. Slightly lower weapon skills than the guard.
I generated the Guard to have skills like streetwise, insight and other useful town skills.
Also he had a decent INT and CHA (around 12-14 ish I think)
His STR was fairly good but a lowish DEX maybe around 10. I know he ended up with 2 CAs anyway.
His actual weapon skills were not too bad, somewhere in the high 60%s
And he ended up with a +1d2 damage bonus, which the barbarian didn't get.
Generally if he could hit, he would do more damage and he had better all round skills, including weapon skills.
Anyway, we set up the characters so the barbarian would lead, sneak around etc.
the guard would follow and be ready with a bow at first.
So barbarian played in a pro-active fashion / offensive
Guard played in a defensive, reactive fashion.
All in all it worked well, a harpy swooped down on the barbarian and the guard did a holding action waiting for something like that, so having more CAs wouldn't have been that useful.
In the wilds, the barbarian was in his element, what with survival skills etc, but actually the guard had a bit of survival as well and his social skills were very good for a starting character due to a decent CHA and a good INT as well.
Also when he hit, that extra 1d2 helped with damage on top of his 1d8+1 for the sword.
That and he had better armor, which slowed him down , but a lower Strike rank is not so important when you're avoiding melee combat.
The difference in CAs showed more when they got inside the windmill and the rounds and actions were still counting off and loads of climbing, evading, hitting and other things that required usage of CAs.
The barbarian outstripped the guard in this regard.
Still, in both cases the guard with his decent to chance hit and higher damage generally got the killing/disabling shots with a bow (which he changed to later) over the barbarian hits, which had slightly lower damage.
All in all, it worked ok for the guard, as long as you don't mind taking a support/reactive role and let those with more CAs get on with it.
Down the track though, the 3 CA barbarian with more experience, meaning more skills increased with advancement points could do the same and probably better than the guard if he wanted.
I would personally conclude, if you want a combat character for Legend, at the end of the day, you really ought to get 3 CAs to be a good combat character. Sure there's ways of compensating with only 2 CAs, but the 3CA character can always do that too and do better.
Especially after character advancement later.
