Multiple costumes
Eventually there may multiple costumes for Rigard.
How will you decide the best path?
The Devs could let you reset your path at any time
([Suggestion] Same hero, free, class node reconfigure or some fun with class nodes)
and when adding that feature, allow it to keep track of a separate path for costumes.
Reset emblems
I do not use reset emblems because food and iron is lost
Limited options
In the end it will not have much of an impact.
Ranger
It would be tempting to spec Rigard based on his Ranger class because node 8 right is +2% mana.
This works well because Rigard has high defense and Cleric node 8 right is Defense 3% or +20 points for Rigard.
