Quantum's Take

Mera is the first healer you get in the game, and she scales well with your account. There are several healers that are much better than her, but given the high acquisition cost of champions like Starfire and Green Lantern, the only healer worth prioritizing over Mera early on is Krypto, in particular if you invested in Superman. The big downside to her kit is there's no utility outside of raw healing, but she heals well enough to somewhat offset that limitation. Despite falling off late game due to power creep, unless you're a heavy spender, chances are you'll still be using her six months into your account.
