to be fair JIRA does throw the kitchen sink in at the beginning and for effective use of JIRA, your team needs to 1) pick what to use and pick what not to use, 2) commit to it, and 3) have an experienced JIRA person that knows how to turn off everything else, and also 4) pray that JIRA doesn't suddenly turn your preferred usage mode into "legacy" which you can't use in new projects moving forward.
