Why does DC keep trying to ruin Nightwing (Dick Grayson)?

…and how bad is it that this isn’t the worst thing that could happen given the link name?

I know for the longest time it was Dan Didio trying to get rid of the character, but Didio is gone now.

I honestly believe that DC has no idea what to do with Dick Grayson. It might be due to DC cannot do anything to jeopardize Batman (who I believe is the biggest money maker DC has and has had for decades). It might be due to DC just not finding the right creator to carry the character forward.

…and don’t even get me started on Cassandra Cain.
