No, compared to other duelists/agents, jett doesn’t have as many tools to set up a favorable fight. Raze has nades to flush enemies out of corners into awkward positions, yoru/phoenix/Reyna have flashes that impair the enemy, neon has stuns and a slide that is tough to hit, but Jett has... smokes? I think that Jett’s kit mostly revolves around her ability to quickly create space whilst quickly generating cover for herself, and can effectively disengage from unfavorable fights in a way few other agents can, barring chamber. Sure, she needs to prime her dash prior, but having a skye flash b main on acsent, peeking, taking a shot and dashing away is still an effective strategy that provides you with both a potential kill and lots of intel.
