It is tricky in the beginning with lightning mains; I had issues as well. Igniting even two characters is really valuable, and if you use it + bani chakra + other ignite chases, you can ignite an entire team. I'd just say * with it unless it really becomes frustrating and you want to change.
More specifically, Paralysis can be countered partially with Death Mirage and fully with Sakura's megaheal, I think, but I'm not really a Sakura fan. I just say hold off on trying to force combos until the next round.
