I'll be honest, back on live I was a Grav/Kin Controller main, Space Cat, even back when they didn't have double damage to controlled targets. Space Cat was a space catgirl with a garrish color scheme that was kicked off of her home planet for being too annoying. Having kept playing the same controller till I quit the game, I can safely say...
CONTROLLER TRASH
I never even played Defenders. I just know how bad controllers really are. It was always a passion. Not a decision based on functionality. It's bad. They're bad. There are tons of reasons why. Unless successive updates have done something incredibly silly, they have the simple problem of being the most helpful AT to have around in every situation except the exact situations you want help in. At which point they can't even get double damage procs,, and having played controller since near release I can say you may as well expect them to go brawl the target at that point. It is the most fun AT in the game both in gameplay and concept and the worst designed from a realistic standpoint of how the game wants to work. Which is a shame cause it's the closest you will ever feel to being an actual wizard. Terrible at killing but essentially unassailable.
That said, I don't doubt somehow madmen can proc build and power pool their way to success regardless. I don't know a lot about Homecomming itself.
I post this before reading the thread to see just how wildly my opinion changes post research.
