AFAIK, there is not a single piece of relic nor af that is "good" in the sense you could idle in it. Sure some pieces are obviously good macro pieces, but you wouldn't TP in them.

So if SE made the +1 versions of the af further increase their augment on whatever spell/ability the change, then af+1 would be worthwhile.

Otherwise, +1 def/str/dex on a piece of gear I wear for a split second to make my sambas last 30 seconds longer is trash and a pointless upgrade.

But if the +1 also made my sambas last 45 seconds longer instead of 30, suddenly it would actually be worth my time getting.

Otherwise, I don't think any piece of AF or relic that augments a JA/spell gets a further increase in its augment's potency when you upgrade it to +1 version. Just gets more def and stats added on. Which is useless 90% of the time on macro pieces. Sure mnd+ on a cure potency macro piece is good though.
