Jayce Bug
Jayce's Hammer form when swapped to causes a frame drop and can make using ur full combo go off as very sluggish and you can miss small details like ahri's charm and so on when this happens and cant qss it in time.

^ Frames are fine to me too. But it s that split second hitching that we get.
Don't forget the bug where E will sorta negate dashes and translate anything you hit in front of you. And when you press R and sometimes the melee magic damage goes off on a ranged attack.
jayce main here, can comfirm.
Just tested it then, the split second fps drop out of hammer form switch is still there.
i think it depends on the user. For me, my frames are fine. But I had an enemy Morgana say the same thing in an ARAM just yesterday.
Upvoted! Same here.
You can also proc hammer form enhanced auto attack from range, as you're attacking in cannon you switch at the perfect time and you will hit them with your hammer from the range of cannon.
Thanks Everyone for the support thus far , if it will help get ur friends to upvote this as well , this affects a ton of jayce mains though we are a minority , thank you <3 
(sorry there are no better hearts :v )
Yep this happens to me every time I switch to hammer.
YES THANK YOU. IVE BEEN REPORTING THIS FOR DAYS NOW. AND NO ONE'S PAID ATTENTION TO ME ;(
plz fix
yea
well im leveling right now a champ up to 30 and jayce is in the free rotation. if theres a jayce on the map dont matter where when he switches his stance from gun to hammer i have the same splitsecond lag like described here. that bug is known for 5 months why is noone doing anything about it? or are there ways to fix it?
Yup noticed this on mine a few times (not consistently, but happened nonetheless) over the past couple weeks.
Yeah I played him yesterday and got this same issue. I sent a riot support about this issue and they sent me to this forum. Glad to know I'm not the only one.
I've been playing Jayce a lot recently and I thought my Internet connection was just worse this week. I will watch to see if the frame drop happens consistently during form change. Does this only happen when you change to hammer from range or does it happen any time you change form period?
Can confirm you get the similar problems after using your ult as syndra
