Just ran it in game, and it's plenty without Piety buff. You get 32% for UI1, 47% for UI2 in battle (35%/50% outside battle). UI1 reduces fire spell cost to half of base MP cost, UI2 reduces them to a quarter of base MP cost.

I used the following with a 2.19 sec GCD:
Eno > LL > RS > Fire 3 > Fire II x3 > Swift > Flare > Convert > Flare > Transpose > Freeze > Fire 3 > Fire II x2 > Flare > Transpose

That took roughly 33 seconds with a fast MP first tick after the first transpose. The first MP tick after the 2nd transpose was less than a second.

Then the same rotation minus LL and Freeze, took roughly 34 seconds with a medium wait on first MP first tick after the first transpose. The first MP tick after the 2nd transpose was less than a second.

Rotation time is almost exactly the same, total potency is about 5% higher with LL + Freeze. That's pretty unspectacular for 15% off your cast time. I'll have to try it out next time I get arrow for an AoE rotation, but I'm not gonna make a habit of using LL for AoE.
