I can have that without stun. They are also happy if I remove dazed, immobilized, slowed, weakened, ongoing damage and similar conditions. It doesn't have to be stun.Yeah, but in the second part, players of Leaders and Paladins, and such types (you know, players who take concepts around helping the team out) get to shine by doing something other than the healing word. They get to go 'Saving throw to you!' and you go 'Now I can move' and they go 'What a great use of a minor action!' and you go 'Bully!' and they go 'Yay!' and they feel like they've saved the day.
You -are- aware that there's other players in your team, and one or more of them is likely to have taken a class that revolves around saving -your- ass from peril. So... if you're not in peril, what do -they- do?
Chain stun bad. Stun once in a while is good.
And groups should be ready for it when it happens, in the same way that they're ready for dominated, and the ongoing damage, and the immobilized.....
PS:
Obviously, if your group can't handle conditions, you use conditions less. On the other hand... if your group can't handle conditions, then what monsters have you been using?

Our Savage Tides party has gotten a lot of experience with conditions, and with ways to deal them. The Paladin allows rerolls if you end your turn adjacent to him. My Warlord has a few save-granting powers.
Stun still doesn't track as a fun condition. Especially not if multiple party members are affected by it _including_ the guy that could remove them. (But you said that in your post.)
15 ongoing necrotic and poison damage is still more fun than stun. Even if everyone suffers from it. It's exciting, because you might actually die from it. And there are multiple ways to deal with it - healing, granting resists, granting extra saves.
In a 21st level one-short, it also showed that save-granting isn't always enough. The Barbarian in the party had a lot of immediate action powers that he couldn't use since he was stunned, dazed or immobilized and thus out of reach. It was not just enough to give him a save at some point, he needed it at the point he was subject to the condition. And that's a lot harder to get.
