“If you can prevent her from auto-attacking to get her stacks up with (Q) do so, as it will render her (Q) weaker, if she has 4 stacks of her passive she can do multiple (Q) snips. Bait out her (W) with (E) or she will invuln it. Gwen is an AP tank shredder. She has a dash on her (E) that acts like a Lich Bane proc on her next basic auto attack, so countering it with (Q) is very resoureful, as she is dashing blind her. The most annoying thing about her skillset is her (W). It's like Xin and his (R) but she gets it every 22-14 seconds as early as level 2. This prevents her from being targetted by anyone outside of the arena. If you wish to kill her, you will have to either force her out or stand in the radius with her. She can move it with her once. So put the pressure on. She is mobile, but mostly squishy outside of her invulnerability. Poke her hard especially when her (W) is down, staying inside can be difficult.”
“Gets super tanky when you all in her. Do not all in her. I have lost a lot of all ins with sheen. Just focus on farming to Sunderer and grouping with team. Also I need more experience in this matchup.”
“I have played against Gwen twice, so I will update this matchup with more helpful advice when I face it more.
For now, it seems that Gwen sucks into ranged champs.
The main goal is to bait her W, and if she uses it, blind her and then walk back, Her W lasts 5 seconds, and I typically just wait for it to expire before engaging on her.
If I blind her she can't even hit me, so even though she is untargetable, I am too with blind. Play really aggro, and play around her W CD. Do not dive if her W is up.
“Take Conqueror. I think onces Gwen settles a bit she will be moved to a 4 difficulty. Rush botrk. Gwen's base armor is super high and she is also able to take TP with Ignite so it's super hard to fight her in a 1v1. Use E+W together or she will probably dodge your W with hers or her dash. Her level 6 is strong so I wouldn't recommend fighting her until you get your first item after 6. ”
“This lane is pretty Darius favored. Bait out her W immune and all in her. She can't trade with you as long as you don't take too much damage while she is immune. Pull her back in when she tries to leave W or dash away , as long as you don't take a full stacked Q from her while she's in her W this should be a favorable trade every time.”
“Pre 6 you should win easily by riposting her Q scissors. It is fairly easy to see the animation to riposte, but you can also predict her to use it when she builds stacks under her health bar with auto attacks. You win extended trades with vitals. After 6 you can riposte her Q or her 3rd ult of needles.”
“You have to fight Gwen from behind or aside to avoid her frontal cone attack such as Snip-Snip(Q) or Needlework(R). Purely a skilled match-up based on if you can dodge her skillshots. Try to force her out on her Hallowed Mist(W) so she doesn't get defensive buffs.
(Sustained 1v1 Trades: Even) (Outscaling Edge: Gwen) (Recommended Items: Thornmail or Morellos)”
“Her ganks are not very good, when you see her, just back up. She is melee anyway and has no slow in her kit exept her ult”
“Gwen is pretty much the AP version of Fiora. She is a duelist with true damage, quick dashes, and high survivability. Even though she is a great pick for an AP top, Fiora should be able to completely shut her down in lane as Fiora is the better duelist. TIPS:  Take advantage of her weak early.  Buy executioner once she buys Omnivamp.  Parry her stacked Q to block true damage. ”
“Only Cons going against gwen, is you cant long range E2.”
