Don't Quit on BC relics
While I find statcast relics enjoyable, I just can't find them having a better concept than battle cast relics. Battlecast relics require specific champions and abilities to work, which is inconvenient and slightly annoying, but when you do find a good pair the difference is definitely noticeable and ends up making the champion better by a great amount. Statcast relics on the other hand focus on enhancing stats rather than abilities allowing them to have easy access but also turn out bland, it doesn't feel like I'm making my champion more effective, rather a background boost that I won't notice most of the time.
Finding the right combination with a battlecast relic may be a bit tedious but the payoff is having an overall better working champion, Statcast relics just don't feel like that for me.
