Random: 80's metal making a comeback.

Does anyone else think metal bands from the 80's just shouldn't be putting out new albums anymore? I mean...the metal scene has changed a lot in 20 years. Dont get me wrong, I LOVE Megadeth and Metalica, they are huge influences in my playing, but maybe they should just keep their dignity, reap what they've already sown, and fade away while they are still respected. Could you imagine a tour like Megadeth opening for Asking Alexandria/Miss May I? even bands like All That Remains and Atreyu, which are more melodic would be awkward to see with them.
