Don't get rid of things - don't cap things. Work to make potentially unbalancing things as hard to accomplish as possible and to balance them as much as possible.

For chameleon, for instance, combine making the ability to get 100% so hard to accomplish in the first place that only the most powerful (and thus inherently unbalancing) characters can get it with ways for the game to deal with it that make it less unbalancing. If chameleon was hard to accomplish in the first place and 100% was that much more hard to accomplish AND if NPCs reacted to a suspicion that something was there by casting detect life or dispel (or even just by feeling around blindly or taking swings at empty space in the hope of hitting something), that would go quite a ways toward balancing it.

Yeah, I've never had any problem with 100% chameleon in Oblivion. Why? Because it was incredibly boring. (I've played enough characters that I must have done tried it at some point. But I don't remember, it's been so long, and I have no desire to try again. It just doesn't sound interesting.) But "I think it's boring" is no reason to not allow other people to try it.


(I also honestly believe that Beth included stuff like that on purpose. Why? Because these are the same people who stuck an infinite-stealthboy armor in it's first FO3 DLC. Fantastically broken and boring, much easier than getting the same effect in Oblivion or MW, and they made it deliberately.)

Do I really need to repeat my post, I mean we all know the problems that Oblivion has or heck the whole Elder Scrolls series has with Exploits. Just because it's there doesn't mean you use it is a terrible argument because people will exploit the game in order to make it easier. Heck if we have a glitch in Skyrim that allowed you to get to level 50, pick 50 perks automatically, and got all of your skills up to 75, everybody would use it every time (Me Included), I bet Todd Howard would use the glitch if it was in the game. Exploits are bad and we need to get rid of them, I still want the game to be a challenge at level 50 not automatically kill something in one hit or turn invisible, get behind opponent, go into sneak mode, and then Whack repeat.

To be real honest here, this is [censored].

If there is a glitch that you can abuse to get from level 1 to 50 or some potion that will turn you invisible 100% of the time. Who cares?
Because in the end, it's a single player game. You decide yourself how you want to play the game. You can even download mods that would make you "god" in the Elder Scrolls game, so come on.
What people want to do in their own single player game is their business. It doesn't mean you have to do the same.

Honestly, I would never 'cheat' in any games because that kills the joy for me. Really, it does. What's the challenge!
So if there is a glitch or potion, you avoid them / ignore them if that is what you want, that easy. Shocking, I know. That hard!

if the NPCs are smarter then oblivion, Chameleon might not even work as well. 100% though i think is a bit much.
