She gets less exp because you aren't using a full fire team. If she's getting less exp while your using your water in the cuss burst, it's probably best to just burst her regularly, will probably save you time and sp til you can get your other fire an erem.

try to examine if she is actually casting fiery.
make sure that the food you are using for your cows will not fully recover the hp. even if the hp is lower than 500, if they are full then she will not cast fiery. set the box to 'Ally'. if she still wont cast, try setting it again and confirm, sometimes the emote does not work properly. check if she cast them on cows and not players.
other than that, vic should get more exp on cuss burst.

also you might remember the exp on normal burst on 2x and you do cuss burst on non-2x.....

Maybe (s)he is sitting while she is bursting, but they said that her Victoria still gets exp, it's just lower than with normal bursting, so it sounds like the bursting is going properly, for the most part.
