Borderlands 2 Headhunter 1 to 5. Buy or no buy?

They are pretty mediocre

no, they don't worth

I have moxxi headhunter and it's only 1 hour mission

i dont regret buying them at full price, i found them fun

dont expect it to be lengthy though

I played them as a level 61 on normal difficulty. They were all set at low levels. I one hit killed everything, including the boss of the last one, which felt really good:) I'm not sure what they scale to on higher difficulty levels, but I'd recommend playing on the higher difficulty so it isn't that easy. None of them are really good, but the Crawmerax one is my favorite. I didn't like the Wattle Gobbler one because of the worst side mission ever.

If you can get them for cheap, go for it. There's not a lot there, but it's more BL2 and you can make it fun by bringing friends and messing around.

You should try history missions like Tiny Tina Dungeon and Dragons dlc (I don't remember the correct name) but this one is EPIC!
