All seems good so far... but like I see.. for example Thorin´s needs a bit more spice, every named dwarf got somesort of special rule or least a pair or 2 or 3..
Durin got a couple of rules, Dain as well, I do beleive thorin shoudl be a bit better at it...
I would give Thorin fight 6, equivalent to Gimli and Durin, cause Dain is old so his fight is a lil bit more rusty(fight 5 for him)...
His weapon seems fine, but I would give orcrist as basic weapon, his defence should be 7 not 6 on dwarven heroes if you notice
and can use mithril armour(that will increase to 9). and its cost would be around 130 or so rather than 110
Cause if you notice this way compared to 125pts Dain he would get +1 to fight, -2 defence (that will be increase to 9 for +15pts) rest is the same with less courage and fate, same rule of the stand fast, the axe gives him the bonus of +1S vs orcs (would be more fun however if that weapon would give +1 S and re.roll to vs orc/goblins and uruks.) got no agile penalty
About bilbo 1 thing to correct... mithril coat shouldn´t count as heavy armour, as text refers it to light as a feather
, specially a small jacket bilbo wears
About his profile S2 is ok, D2 not so much, bilbo with defence 2 means hes older, this version hes younger, so I would give him defence 3 basic just like frodo
I would give him a rule related being good as reading maps and such, in game? maybe something to allow you to re.roll who win the iniciative order
Remain dwarf heroes, if you wanna give them defence 8 in general with upgrade, I would give them acess to heavy armour, cause I doubt all would wear mithril armour
