What’s up with the Co-op

I really don’t get what the game designers were thinking when they decided death will end some co-op types (which 90% of the time I’m getting called in as a visitor).

I’m trying to be social and help people, but so many games the summoner will walk into the white stuff in crucible/inferno and its over faster than it took to load the level. Or they die early in another way.

Then again, It’s even worse when you’re helping someone throughout the whole area and you’re separated because he dies on the boss.

Am I not getting the point of this? Am I in the wrong and you guys actually consider this a good mechanic?

I really hope that TN will reconsider. Love the game, but the multiplayer could use some refinement
