does anyone feel that the mysterious map is all a con and misleading players?!

What's the deal with that one? Had it yesterday as Tank and saw it grows, grows and then is small again and it starts growing again. I stunned it on its way to get bigger but didn't notice any more dmg or something. Does this thingie explodes if it is not stunned or what is it about?

For the bomb that grows you just stop dps until it shrinks back down.
