IndeedIs it just me or did 4th edition ruin everyone's sense for what is overpowered?

I think it shows just how incredibly well balanced 4e actually is.
And if something 'overpowered' does slip through, it gets errata fairly quickly.

If I ever play a shardmind, I'd choose to have the best of both worlds.
Does telepathy allow you to overhear the thoughts of a creature that isn't trying to communicate with you?
Eg. Could a shardmind translate the battle commands of the goblin warlord who is shouting in Goblin, even if Goblin isn't one of the shardmind's languages?
I haven't seen anything that indicates either way, but I'm inclined to rule that it couldn't.
Furthermore, telepathy won't help you read the BBEG's careless notes to his followers that are written in giant/abyssal/language of choice.
It's a small niche perhaps, but a niche nonetheless.
I am pretty sure based on what I have read that you can only communicate one way so you can telepathically talk to someone but they can't reply back in your mind it would have to be verbal unless said target of the link could also use telepathy. Just my .002 cents *verizon joke*
I'll wager most people posting here are away from their booksWhen in doubt, look the damn thing up.
Also, and this is vitally important, you get to mooooooo as you move around the board!
telepathy: A creature that has telepathy can communicate telepathically with any other creature that has a language. The other creature must be within line of effect and within a specified range. Telepathy allows for two-way communication.
Does it state whether it has to be willing two-way communication? I presume that it allows the creature with telepathy to communicate to another creature and hear its responses, but not to eavesdrop on its thoughts?
n.b. the definition introduces a little bit of conceptual weirdness, in that telepathy doesn't work through a glass window. Personally I would have thought that it makes more sense for it to work within line of sight rather than line of effect, from a traditional perspective.
