"IRC, otherwise known as Internet Relay Chat, is one of the oldest and most popular forms of Computer Mediated Communication. Developed far before the World Wide Web, IRC is one of the largest uses of bandwidth on the Internet. Invented in 1988 by Jarkko Oikarinen in 1988, the program exploded in popularity."

To be fair, most people these days use discord. Users would more likely shy away from an irc server rather than a discord server. To put it simply, irc is a bit out of date. I would also like to point out how successful these non official discord servers have been which can weaken or strengthen this suggestion depending on how you look at it.

Edit: We wouldn't have to get rid of IRC if a discord was set up. I just believe appealing to the newer members is a good idea. Especially for support.
