No, the contrary.
As Di said we want to be able to kite and dispel. Right now you either do kitiung for surviving, or dispeling that's your job, both at the same time is impossible, cus you have to stay still to cast.
You can kite and dispel atm though. The only time you should have a problem dispelling, is when a Ranger/Sin or an Archer/Hunter is on you since they - Auto Auto Auto - compared to fighters/warriors and defenders/guards who -Move auto Move auto Move auto.
Even then, if you kite out of range of archers, they'll have to chase you into fury raid and die and then you can dispel freely. And with rangers/sins, just kite around dps til they notice and kill them in 2-3 hits (if anyone needs a buff, it's them).
If you're having trouble kiting and dispelling just normally, use mount, it's possible to do it without mount but mount makes it much easier.
