Why do people avoid getting better at the game?

[TaleraRistain]

On very easy the objectives are all close to one another and mobs die faster.

That doesn't sound too horrible of a change. Especially if normal is still there for anyone who likes it. Helps people get through where stealth isn't really their thing.

Because it kind of is.

No matter how nice you are wording it, you are lecturing them for their wrongdoing in front of at least two other people.

Stuff like this should be handled in private, but of course we can't use /tell inside dungeons.

Or just asking first can be really effective. There will always be those who will get angry no matter what you do, but if someone is an active part of the interaction and asked if they want advice and agree, they're much more receptive than having some random person just start finding fault with them in front of others. Nobody likes to be dressed down in front of others. That's why management training involves how and where to speak to your employees about issues. And one key factor is not doing it on the floor.
