kog'maw basic attack

i have noticed a problem with his basic attack animation on lion dance and maybe others (untested) the 5 attack speed animation is still in places and pressing w feels to slow down the attack speed it might just be the animation but his old animation not only looking cooler with and without w. the problem is when you press w his (tongue)? has to extend all the way out and with less attack speed takes longer to do. slowing down the attack where the old animation which was a fire ball was just instant like the basic attack. plus the old one looked cooler on both w and without w maybe you just forgot or have not got around to it yet. but is it slowing down the attacks when orb walking or is it just the look and feel of the animation?
