A lot of my SG mates did not care for Mind Controllers, because of not having pets. In fact, none of my SG mates played a Mind controller beyond 33. However, since SoH controllers likely won't have pets until after Commanders are released (probably 2nd major patch after release or about 6-8 months), Mind Controllers would be the template to work from, at least at first. I still think that the best way to make controllers is to make their mez powers better than CoH, give them some perfunctory ranged attacks in their primary, and not run pets at all, or at least drastically shorten their timer so they only exist for a minute or so.
Why? Because Controllers were too damn weak early, and too damn strong later. Everything was about the pets, and IMO that is not what should define them. They should be defined by their ability to control the battlefield, not by how their pets can wipe the battlefield clean while the controller has a cup of tea.
In almost every other game with a controller type AT, they have some ranged ability. CoH Controllers only had significant damage capability from temp powers and pets. I think this is one area where SoH can set itself apart from CoH with a better AT.
I level capped an Ice/Emp Controller and was working on a Fire/Therm when the game closed. Got that one to 41... If the game had continued I was very interested in making a Dark/Dark Controller. Even though I prefer melee based characters in just about every mmorpg I have ever played, I was rather fascinated by the way Controllers played.
I agree with GladDog. Controllers should not be defined by their pets. In CoH the Controllers had pets before Masterminds existed. I am of the mindset that Controllers should not get a pet.
Controllers will need some way to do enough damage to solo. I like the ideas of including a few single target damage attacks within the control powerset. Improving the damage on single target controls is another option. On my Fortunata I slotted Dominate for damage instead of hold duration. I think the Fortunata single target hold did considerably more damage than the Controller and Dominator single target hold.
Do we know that Controllers will be a Control/Support archetype? I always preferred playing on Dominators. If the SoH Controllers get a few damage powers in their primary powerset though, I will be much more interested in playing as a Control/Support Controller. If a hero can do sophisticated things like caging enemies with elemental powers, why would they not be capable of blasting enemies with those same elemental powers?
"Hey Sonic Corona! Can you blast that baddie with fire?"
"Nope, I can only materialize rings of fire around his feet, and scream at him to lower his resistance. I am not capable of shooting fire at him."
I might have enjoyed Controllers more if I played a more effective combo than Fire/Sonic. I was always hurting for endurance. Too many toggles.
