Hi Lukros, what you are saying sounds so familiar. My two favorite AT's have always been brutes and dominators, and honestly I had never had an interest to make a controller since I always associated them purely with team play. Well, when time manipulation came out, I realized an illusion/time controller just sounded too cool and rolled one. She's only level 29 but beats all of my dominators out in terms of fun and currently is my favorite character to play! I can't wait to take her into groups now that I'm been being more social in the game.
The only problems I'm finding I'm having with her is soloing elite bosses, such as the Who Will Die? first elite boss that you fight, I just couldn't do enough illusionary damage to the boss quickly enough before he regained it back. If I plan better I'm sure it's possible, but at the time the EB and I just ended in an irritating stalemate. Either way, all other content so far has been smooth, you're bound to have a great time with yours.
