In the current iteration of the game, conditions are way oversaturated and boons are far too accessible. For example take Ranger, power can be fun. But if you want stupid strong condi is hands down better. First off there's traps, which of all their skills can save you in a pinch and hit multiples. But on offense they can tear down opposition without struggle. Then there's the pet, condi pets just outperform their power counterparts in both damage and use. Lastly it's important to note that against adds condi always outperforms power since damage can be spread more easily. Though I love them, Necro is just crazy powerful as condi. And this leads me to the problem with saturation of these buffs, it requires mobs of all kinds to have lots of it to challenge players. With break bars already making cc difficult to impossible on some mobs for a average power build. When every Awakened mob not only does cripple and slow conditions sometimes coupled with burning, confusion, and/or weakness it can be a real downer to enjoy content. Especially when the same mob gets Protection, Healing, and Might base. Mobs shouldn't need a spam of boons and conditions to make them challenging, at the same time they shouldn't be a push over. Here's where it gets frustrating though, every expansion seems to start with players getting access to lots of boons and condi that has to reigned in over time. As for the mobs in game that means they are designed for the overpowered professions which means as the balance happens they by proxy get stronger. I've stopped playing several professions for this very reason, I have armor that's the wrong stats and don't feel like wasting a ton of mats on a new set every time they get tweaked. It's no fun constantly changing builds when I already have 20 toons. It seems to me there needs to be a baseline of what is normal, if you need mobs to be harder to kill, I'd prefer they get more health before you go condi and boon crazy with them on such a wide scale.
Just a though on future expansions and content, reign in the conditions and boons so power builds aren't always getting railroaded.
