Heck no! That is probably one of the single largest differentiation factors between WHM and SCH. You get throughput, but you are much stickier in terms of movement.

If you are having so much trouble, grab Virus and E4E from the SCH toolkit (both instants) and use that for temporary mitigation.

Your example on Demon Wall is a bit weird. You just aren't very good at it yet if you and your party are having that much problem with the bees. As a SCH, the only spell I cast is Succor (which has a CT) and the rest of the time is either using Sacred Soil, E4E, or DPS'ing the wall.
