Yknow, its not really an annoyance/etc, but another thing I noticed with the Legendaries and Jackpointers highlights what I feel is a disconnect with the narrative-drama fluff and the ruleset.
When you look at all the jackpointers and shadowtalkers and stuff, they're all pretty much soloists, maaybe pairing up with each other once in awhile. The way they get described in the various ministories in the source books/etc, they're seemingly always running solo, doing entire runs worth of stuff by themselves apparently. Maybe someone like Clockwork or one of the riggers, or Mercs talks about working with a team but usually its not a 'core team' its faceless mooks they're using to fill slots, or nameless guys in a larger merc operation.
On the other hand, as a social game, SR is kind of setup as 'you get a table group and you guys make a team' and unless chars are dying left and right, generally repeat table sessions means repeat chars. I mean, its not a huge deal, and some of the narrative fluff does nicely show 'not legendaries' doing teamwork, for good or ill.
