Do something about the outrageous health pools, and you might be closer to something acceptable. Ultimately, though, some people (such as myself) don't appreciate this being dropped in as non-optional. There is literally no incentive for me to want to deal with these things, so there is no reason I want them to be in the game in the first place--let alone the existing content that I previously could run with a decently geared and thought-out build. I'm not a triple completionist, don't have 6 years worth of raid loot to draw upon, and would rather play an alt than TR. These champions are strictly detrimental to my play experience--as in, NOT ONE GOOD THING about them. If they at least gave some extra exp (2-3% of quest base), I could justify the extra time they take to deal with. I appreciate that they have been dialed back a bit, but they still have lots of problems and are still purely a waste of time.
I tried them out when U24 hit, and I haven't logged in since that day. I have no reason to.
