Everyone has their opinion on what s/he consider interesting and/or boring and I guess the Wolverine comparison might work if we keep 'Ric' "Jason Todd" Grayson, but if we go that route I'm probably out anyhow.
My favorite runs on Nightwing are Dixon's run in Volume 2, Higgins when he finally settled down to world build, Grayson, and Seely's run once he got to Bludhaven. That is what I want more of. To me the lone wolf, no supporting cast reminds me too much of the post-Blockbuster death run in volume 2 followed by the mishmash that came once they moved him to New York and things like the Paragon story in Higgins run.
