>>29826778-Liquid Voice doesn't even boost a move's power. Scald is still your best option as a Water Pokemon with sub-standard HP/Defense. If you wanna pierce Subs do it with a Pokemon whose more dedicated. There's plenty of more interesting options than Primarina for that, like Chandelure.
-Signature move serves almost no purpose, it's Surf that cures burns with no power boost. Might be useful in doubles 0.1% of the time.
-Lack of recovery outside of Rest = poor man's wall. You CAN get away with Rest/Sleep talk, but do you really want to? Of all moves, Snore would actually be a saving grace here if Primarina were faster.
-Bad concept/design, in my opinion.
Only thing it has going for is its decent typing.
It's OK for in-game but there are so many better Pokemon out there (both in usage and design). This gen/region is chock full of neat/amazing Water and/or Fairy types. No need to fill that niche with a sea lion wearing mascara.
