Elites are good, they make combat/game play more varied. Mixes things up. Keeps you on your toes.
They fixed Inferno crowd control abilities a long time ago, it's hardly even noticeable now. The first cast is full duration, and if cast on the same monsters, for the next few seconds duration/effectiveness is reduced, then returns back to full. I've used Temporal Flux extensively, if there is any reduction, it's hardly noticeable to me. Monsters are moving pretty damn slow, even with the nerfs.
All of your suggestions would only add up to an easier game, not really a better game (and certainly worse in some players eyes).
Given that full-duration CC trivializes inferno difficulty, I assume you want to see CCs nerfed for all difficulties, making them a clutch tool for getting out of the sticky situations people often find in Nightmare difficulty?
... and you're either proposing that trashmobs take as long to kill as elites, or vice versa, but I can't figure out which option is the good one.
Elites still walk through slows and stuns like they were never there, therefore a dps increase or damage mitigation ability on your bar will always be better than crowd control. It makes the combat a LoH/LS snoozefest.
Elites are too strong compared to regular monsters, and since you have to at least balance for Elites the white mobs end up being trivial. I don't want Elites to be easier, others stronger (doesn't apply to all mobs, but most). Bosses could also use a significant buff.
Affixes with both STR and INT, or STR and DEX, or DEX and INT are not healthy, you can have bad affixes, but you cannot have trash affixes. STR+INT and those other two should see the way of "Light Radius".
Having cooldowns of any sort is not healthy, resource [re]generation should be the cooldown.
"Balancing" the game around the people who break it is especially not healthy. The dev team has been hard at work hunting and patching to save Diablo from cheaters and exploiters. Hours, days and months they could have put into the loot, the combat, the runes, the affixes, all of which would be more beneficial to the health of Diablo than it is at the moment. Let's hope removing the RMAH will refocus their attention at the right place, improving the game as opposed to policing it.
It's not healthy to have a 70 to 80% reduced effectiveness of snares and affixes [and others] in inferno. It's not healthy for Elites to be significantly stronger than regular monsters. There's a lot of things that ain't healthy Wyatt, welcome to the monster you have helped create.
