so like right now? 
that’s why she’s currently so niche and bad rn: incapable of getting uptime for her job reasonably independently unlike many other heroes that can and needing to drain out her team’s resources for to get that uptime.
current tp (as bad as it is) at least leaves some opportunities to let sym get some uptime for herself. but removing it straight up leaves 0 for herself.
orbs rn are objectively bad. sure it was worse before 3.0, but doesn’t detract from how bad they are now:
literally a sniper-tier low firerate (encourages aiming) but they’re so slow that aim physically matters very little in landing a shot in most ranges despite the projectile size.
If you want a numerical proof of that claim, expand and see the numerical proof section of this post.
no. a sym without mobility is only ever going to get within effective range of enemies if she get team pocketted in which case we’re likely talking about w+m1 (12m) in which case she’s not going to have a say in whether she escapes or not unless she’s throwing, the team decides that for her as they’re the ones enabling and facilitating the engagement.
and when your entire team is 12m from the enemy, either it’s hard commit to team wiping them, or risk dying trying to get out. i.e. sym doesn’t disengage with that build, she simply doesn’t have the tools to, she’d just w+m1 until a team wipe or she dies. and that’s exactly how it played out with old sym.
