I think it's time you let tristana move with her W without being affected by CC or displacements. It feels super bad when you use it to dodge something like a blitz Q and he grabs you anyway halfway across the lane and around the corner only to throw it on CD and be set right in front of him.
Make her W an iFrame, please.
Jinzo Torrance1 votesIt feels super fucking bad when as 
you grab her during the fucking CAST TIME of his W and she just jumps away, same BS as Ezreal E. They should just let that CC stops their escapes, so fucking annoying. " hurr durr Blitz unstoppable force in bot lane (in silver elo) hurr durr ulti nerfs, Q nerfs"
I hate my ADC1 votesThe Blitzcrank only has himself to blame if he tries a pull before the Ezreal used his Arcane Shift. Blitz can easily sprint up to Ezreal to force an Arcane Shift and follow it up with a pull. Also, you shouldn't pick Blitzcrank if you don't know which ADC and/or support will be on the other side.
Blitzcrank has many hard counters. If you find the Ezreal's Arcane Shift bullshit, I can only imagine what you must think of Sivir's Spell Shield and Morgana's Black Shield.
Jinzo Torrance1 votesIf you grab Ezreal while he cast his E, you will deal damage but he won't be pulled to you. I'm saying cast-time shouldn't negate CC applied during it and proceed to still have their escape go off, their cast time should be interuppted and their escape negated.
Sivir and Morg are more different, Sivir E and Morgs are instantenous and I have no problem with them. Ezreal and Tristana have a cast time.
I hate my ADC1 votesNo, Ezreal and Tristana are instant. The animation isn't. Once they casted the spell, no amount of CC is going to stop it from happening. Just like Ezreal's ult and Lux's ult doesn't get stopped from CC or death. You could kill the Ezreal, if he Arcane Shift before dying, his corpse will still move to the location of his Arcane Shift.
That's how the ability function, there are plenty of ways to play around it, it doesn't make Ezreal or Tristana too strong. If you play Blitzcrank, bait the blink/jump by sprinting at them. Blitzcrank isn't all about standing back and throwing a pull in hope of hitting someone. Good Blitzcrank keep their pulls for after they fisted, not before, unless they have the opportunity to pull. If you try a pull and miss, you place yourself in a situation where the enemy bot lane can punish you and your ADC because you are out of options.
Jinzo Torrance1 votesWhatever, you can't always bait. Pressing W and running at them works in silver, you're gonna eat damage at higher elo. Blitz looks for holes between minions, understand how you move, when you try to bait his grab by leaving the minionon wave, they home on you, hoping that you start stutterstepping so their ADC start hitting you for free, and they pull, AA and reset with E, it's not always E Q, sometimes it's Flash>R>Q against Sivir or Morg. Also stop telling me how to play Blitz, the argument was about escapes with a cast time beng interruptable, I just don't understand why Tristana W behaves that the cast-time is interruptable but the dash is, it seems unfair to me that mid-grab she jumps away.
Also they are not instant, Vel'koz W, Syndra spells are instant but have an animation to it, Tristana Q doesn't have a cast-time, her W does, Ezreal E too.
But it's clear you find it normal and I find it unfair (on escape abilities), so the discussion can end here for me. Thanks for the insight.
