@ Ross61- No, he hasn't said that but I see nothing wrong with an expansion of Deathstroke's own supporting cast by adding in some new characters for him to go against so he doesn't have to rely on his Titans connections or on Batman either to boost his cred.
@ Nite-Wing- That's why I put the word rogues in quotes. I'm not talking about a traditional rogues gallery at all here. What I'm talking about is an expansion of his supporting cast particularly people he goes up against. Having him interacting with the heavy hitters is all well and good but it doesn't really benefit the character in the long run because then writer come to rely to heavily on those heavy hitters to make Deathstroke "matter".
@ Barbatos66- It's only difficult because a lot writers these days don't really bother with it anymore. They just throw characters at the big guns and call it a day. If Deathstroke has a fair few villains of his own then someone needs to start using them and building them up and maybe add to the list as well. A well established supporting cast that writers can draw from would enrich the character in the long run far more than an encounter with the "hero of the month" will. All his fighting with Batman means is that they want him to be taken seriously which I feel these days, is unnecessary. He already matters is what I'm getting at.
