I'm cool with tough and challenging. But omg is it rough in there. The dz shouldn't be THAT difficult because you also have to fight players most of the time. Its too easy to let someone do all the work and jump them at extraction. But add high difficult A.I. to it and you may as well just go do some heroic missions and bounties. Original dz in d1 was rough, but not as fun. Part of the allure of the dz is to be able to amass a good amount of loot at the risk of a rogue killing you for it. Super enemies make the risk outweigh the reward.
