Are tongues overrated? Yes, in many circles. Paul in 1 Corinthians 13:1: tongues without love = noisy gong. 1 Corinthians 14: tongues should be limited in gatherings, require interpretation, and if an unbeliever enters they'll think you're crazy. Paul explicitly says prophecy is BETTER than tongues because it edifies the whole church. Tongues as a status symbol or proof of salvation is completely unbiblical.

1 Corinthians 13:1: tongues without love = noisy gong. 1 Corinthians 14: limit tongues in gatherings, require interpretation, stop if no interpreter. Unbelievers will think you're crazy (v.23). Paul values prophecy over tongues because prophecy edifies the whole church. Tongues as proof of salvation or special status = unbiblical. Even Mike (who believes gifts continue) says the tongues-obsessed groups need to read 1 Corinthians 14 and submit to it.
