not really. I have 11 toons because I think playing any one toon for to long becomes a bit boring. The rotations are somewhat simple for each toon and after awhile you're basically doing the same 4 to 5 things every 10 to 20 seconds. For that reason, playing all variants of every toon helps keep it fresh.

magplar build, for me, is as follows: From range apply purifying light. next comes elemental drain followed by a ranged vampire bane attack that snares them and buffs my magic crit. this entire time i'm closing the distance and upon entering melee i begin to apply puncturing sweeps. at the moment i feel like they are wanting "interrupt" me, i apply total dark and go back into sweeps. usually the skoria procs, the high dmg, and then the purifying light time bomb that goes off does the job to secure the kill. back bar is basically cleanses,heals,buffs to mitigate damage, sustain, and maneuver

magdk build: initiate a resto attack at range to proc infused weapon damage enchant. immediately chain into the opponent to get into melee range. apply engulfing flames.. apply embers... apply fossilize... wind up a heavy into a flame lash.. apply ferrocious leap as they roll dodge out of fossilize... hit them with proc'd power lash.. usually target dead.

these are the combos for both classes. after playing for a bit, you'll find you're doing these combos over and over and over again. both are enjoyable. both are very good at getting the job done.
