I think isranged causes the spell to use accuracy vs (dodge+dodge vs ranged).
Why not just give path of the mage some crit as well?
well usually mages are supposed to have big base dmg spells and aoe etc
there is nothing really against spell crits but then the system should be different
many low cost low dmg spells for each fight for example so that a lucky 1 shot crit cant happen (btw in the actual system you can 1 shot even with normal spell... )
also crits shoudl be reliable and less damaging, so theer should be crit talents for mages too
it seems just overcomplicated than just removing critis and keeping the actual balance even if it could be nice once the system is well balanced
