Stunning And Slowing Enemies

So, as someone who primarily plays an aggressive Mage and Assassin, I find my playstyle very dependent on the disabling elements of the Spin Attack, Multi-Hit, Smoke Bomb, and Ice Snake spells. However, with the update it seems like the slow from the Spin Attack and Smoke Bomb are almost nonexistent, and I've yet to see an enemy stunned by a direct hit from an Ice Snake. In addition, I can no longer throw enemies out of close quarters (or move them at all, for that matter) with a landed Mult-Hit. This sorta cripples me in combat, especially given I've not yet optimized my two main classes (Mage lvl 60, Assassin lvl 63) for damage with the new element system.
That said, does anyone have any idea as to what my issues might be stemming from? Is it an intentional nerf? A result of lag? I'm rather curious, as it's actually resulted in my death three times at this point. *gasp*
Thanks in advance for your assistance.
