Unlike the Great Weapon Fighter, it wasn't love at first sight with the Control Wizard and me. In fact, I originally thought that their movement animation with their weapon (orb) out looked really weird and off-putting!
However, seeing other players play this class changed my mind about it. Their range of AoE abilities in particular was awe-inspiring both in terms of their animations and their effectiveness, ranging from the summoning of chaotic maelstroms to lightning and blizzards, with enemies getting knocked every which way with every cast.
Like with the GWF, I was pleased to find the class easy to get into as well. The tab ability simply offering a fourth encounter slot (with a modifier) was as straightforward as it gets, and the clearly themed abilities were easy enough to figure out for me to create a serviceable build even without a guide. I did occasionally find myself struggling with survivability, but simply trading one damaged-focused encounter power for a more control-focused one usually did the trick.
I can't imagine that running around on my Control Wizard and AoEing down enemies would ever get old. I still love Shard of the Endless Avalanche for example, aka "the purple ball", even though it's a pain to handle and I had to unslot it ages ago, but the concept of literally bowling my enemies over is just too much fun. Even without it, it's a great feeling to watch whole packs of mobs alternately get stunned and damaged to the point where this character was my first damage dealer that could run without a healing companion because the mobs could barely touch her anyway. Large single enemies with a lot of hit points or control immunities remain a bit of a pain though.
