Counters to Tracer’s pulse bomb or significantly reduce its effectiveness.
Zarya Bubble (Anyone), D.VA Defense Matrix (Anyone), Wraith Form, Fade, Transcendence (Zen only), Sound Barrier if timed extremely well (anyone in range), Primal Rage, Bastion’s Tank Configuration, Roadhog’s self heal, Orisa fortify, Sombra’s translocate, Tracer’s recall, Mei’s ice block, Torb’s steroid, Doomfist’s ult. Am I missing any? Thanks to the pulse bomb nerf she gets a whopping 2.7 kills per game in comp with it.
Pretty sure Zarya can do her thing even after Tracer’s stuck a target. No preemptive actions needed.
Things that can one-shot Tracer.
Everything that can one shot 200 hp heroes.
Everything that can one shot only Tracer (Or… Pilot D.va… I guess). Mei’s head shot (which has gotten buffs thanks to more ammo, no fall off, and faster projectile speed. Oh freeze also lasts longer), damage boosted Widowmaker/Hanzo body shots, damage boosted McCree headshots (no flashbang required!), damage boosted direct Junkrat grenades or mines, damage boosted direct Pharah rockets (make sure to dive down on her from above for maximum effectiveness and reduce projectile travel time!), Damage boosted Soldier: 76’s direct helix rockets. Torb’s alt fire (must land all pellets so get in close), Damage Boosted Torb primary headshots. Half charged Doomfist Rocket punch (Must have wall impact as well). Reaper landing 11 (one more than half the total amount) pellets as headshots or 16 pellets as body damage and 3 as headshots (that’s right he still doesn’t need to land all his pellets!), Roadhog landing all his pellets as body damage or half as headshots (No pesky hook required). He’s more consistent now making this even worse for Tracer. Also Ashe can one-shot headshot Tracer without any boosting like Mei except no need to account for pesky projectile travel cause hitscan. Damage boosted dragon blade or nano blade which is all the rage these days I hear. Remember no amount or mobility or Recalls will save you from getting one-shotted!
I’m sure there are tons more via combining damage boosting, discord and nano boost in various ways. Such as Reinhardt’s melee (needs all three), or Fire Strike (just damage boost and discord.)
Nail in the coffin is a successful Sombra hack can take away her defenses to avoid all of this. Which if you can’t get off a .65 second ability on an unaware target (You get to control when and where you engage with Sombra thanks to stealth) Sure, thing is Tracer needs to get within her range to do any kind of meaningful burst damage. Also, flashbang does work since Tracer has to get within its range to do damage. Also, McCree has combat roll on a lower CD now if Tracer’s is being cheeky and dancing outside its range. McCree’s should not be rewarded with a dead Tracer for missing their flashbang end of story. This goes for Roadhog’s who miss their hooks too. Maps, flanking routes and objective points force Tracer to play in the danger zone more often than I would like and limit her blink range (Don’t want to blink off the sides on some maps after all). I get caught blinking on geometry on the maps a lot of the time.
Biggest thing I can say is Overwatch is a team game. Not 1v1 death match in a vacuum Fox only, no items, final destination. Tracer’s mobility DOES NOT make her immune to damage at all or even abilities as I have been hooked and flash banged mid blink countless times. People like to argue that she can just blink and avoid damage acting like it somehow makes her immune to everything and that’s all they need to argue. That’s way too simplistic. That’s not how it works in real game play, trust me.
Incidentally both Zarya and D.VA can stop Tracer from one clipping anyone.
She can’t recall or blink out of flash bang/hook/Shield bash as an escape, she can only avoid it.
Neither her average 2.63 competitive kdr, 1.72% pick rate or 48.70% win rate suggests that she needs either counters or nerfs. I’d also like to point out that Reaper does more damage per game, and heals more per game then Tracer does with recall. He also has effectively the same KDA. His ult gets more kills per game. Also there are tanks that do more damage per game then Tracer does (Dva who also gets more eliminations, Zarya, Reinhardt is comparable to Tracer, and Hammond. Roadhog as well with 10% less accuracy.)
The average is 36% competitive accuracy on Tracer. She doesn’t one clip people nearly as often as people thinks she does. Cut that 240 down to around 86.4 and you have a more accurate number. This is why people think Tracer is op is they assume 100% accuracy all the time. That’s just not the case.
Hope this helps.
