I solo a Ill/FF controller for fun. He's up to level 31 now, and I've had a wonderful experience doing all the missions so far.
I know I'm in a small minority, but I *like* soloing a controller. I tried a mish in test to check the changes out. I was fighting yellow and orange sky raiders, with red and grape jump bots. Whew, quite a challenge normally.
I rescued an ally, and he was pretty cool. I could wander around invis and he'd follow. Some things I noticed.
*he'd retreat when he got hit too hard.
*he'd one or two shot minions, and remove whatever XP I was going to get for that mob. Seeing as it takes me a lil bit to arrest villains (even with changes) I thought this was a bit unfair. I'd rather make him wait until I needed him.
*He'd agro mobs I didn't intend to agro, especially when I took great pains to get around them. lucky I have PFF, or I'd have been toast on several occasions.
*I could bubble him. very cool.
*the extra damage from my powers was good enough to allow me to defeat a boss I couldn't in I4. the ally helped that a bunch, but I lost XP. I might as well have confused some bosses and whittle down my opponents for me.
Overall its a mixed experience. Made the mish go faster, (only an hour long, rather than the 2 hours it took on live) I welcome the changes to spice things up.
* I'd like more control over my ally, as he is an annoyance at times.
*I'd like to be able to say 'stand here', 'wait', 'follow' as well as 'attack!' and 'retreat!'
*the XP thing I think should change. yes less because he's helping, but maybe a percentage down like in a team setting, as opposed to not getting credit for his kills at all.
Theres my 2 cents, thanks for listening.
