I'll make the math simple so even the geniuses can understand.

1) there are 14 rune categories, add +3 for the combined effect runes, = 17 rune types needed.
Need 5 of each to have full sets. = 85

2) you have 12 bodies, at L60 they have 5 slots each = 60 slots.

and that does not include any work space to store and manage.

Even at 8 slots each it doesn't work.


BTW in order to use the "combine all" i MUST clear the rune area onto bodies ...

otherwise I'm moving 60 point runes around one at a time trying to build a 7000+ point rune? ... or 15k, or 60k , more?!?!?
conclusion:
it is totally impossible to manage runes this way.
