You are right on this one. While trying new stuff may discovergreat synergies and counters, but you shall not go too far, if you are playing to win (e.g. rankeds). Just as you wrote, a Janna top may be perfectly viable. An Irelia mid built as an AD caster may be the worst you could face in the midlane. Anyways, just as you said, the team comp isvery important, and therefore trying new things in premades may be more benefical.

All in all, you should give everything a chance, but if it does not work out, you should leave it :)
