There are blatantly better ones. Light Nike is under the "ok" category in terms of tier, since she takes forever to actually get anything going.
Tishtriya comes directly after Nike, so if anything I'd suggest you go after her rate up instead.
Speaking of tish, here's a ping to all using slashley's encyclopedia for you to reconsider her usefulness:
Skill 2 uptime and cooldown is mixed up. She casts all those offensive buffs lasting 5T, and has a 3T cd on the skill. That's actually borken.
To be fair, all light himes released after Tish are all pretty solid as well. Especially look out for Lugh and Iris after Tish.
