By the way, I just ran into another situation where Allies Roll is useful. Primeval Brew. Chaos Roll is useless with capped attack, if you're not using a WS that can crit/DA (i.e. any magical WS), that eliminates those possibilities, Store TP and Regain are fairly irrelevant when you're already hitting 50tp/tick.

I brewed Rani on COR with Aeolian Edge - the only two rolls that help are Wizard's and Allies. Self SC with back to back AE (Evisceration -> AE is also a SC, can't recall which offhand). When you're busting out 15-20k WS, the SCs are also pretty beefy and the Allies Roll boost helps increase that big chunk of damage. Killed Rani from 80% in a little over a minute.

Yet again, very situational roll and maybe you don't find it worth 100k+. But not "useless" in the Gallant's roll tier.
