I understand everyone is concerned because they would want their class role to be obvious and necessary.
However the current state of Glory makes us the worst possible tank in the game. I have heard people (new to the game, yes, but still) laugh at the idea of a champion tanking GS. And looking at what is available, it is actually laughable sometimes if you compare it to having a warden or guardian, but then painfully necessary in the new servers where groups form up and you end up seeing "need tank & healz" over, and over, and over again because people have rolled other classes much more.
I agree with Vallik about the guardians, they can now dish out good DPS, and anyone who thinks we champs could ever pose a threat to Wardens... well, whose quote was it? "I'm a Warden. I AM a small fellowship" pretty much sums it up :P
I understand the concerns over shieldless tanking both in the stuff we are losing and the dps tanking risk we pose, but as it is now even with the shield it takes a lot of skill from the champ and from the others to get through something as simple as NC. Let's be honest and recognize not everyone is a great and fantastic champion, runekeeper, hunter, etc, and finding 3 who are at such a level is more challenging than anything else (again, new servers, people learning stuff) This doesn't mean you carter for the lowest common denominator, but the game is intended to be fun and there are some twitches to the class that are off-putting since the champion can only learn them by being given a chance, and other classes don't wanna waste time doing that and cross it off as "not possible" (back to GS example)
In short: champs need the fervor healing penalty revisited to account for aoe and dot damages at high levels. we also need our tanking stance revisited to make us a desirable tank. Not the "most desirable" tank, but a desirable tank that can actually hold some aggro in glory when our fellows are dps monsters. Just like we are a desirable dps when the hunter is the most desirable dps. I'm sure the devs are well aware of class balances.
ps. cooldowns!
