I would concentrate on your best units first. Upping their damage output and abilities is more important, but you could make a really nice mono-AGL team for events against STR with what you have. It's good to at least buff the "lesser" team members as well. BUT, again, not as the cost of maxing your best units as much as to possible.

Just to clarify, the potential path on the bottom right is the only one you have to level up the SA to open. The top right only concentrates on ATK and SA. Bottom left is def. Top left and bottom right give you your special abilities (dodge, critical, and bonus attack).

If you have a top tier character and only one dupe. Use it on the bottom right, as you'll want to up the SA anyway and that path gives you the biggest bonuses.

For everything else, test the cards out and start with top left path to get first abilities and see if you like how it plays.

I'm no Dokkan Battle expert, but that's what i've come to realize by using dupe system myself.
