How am I downplaying anything? This is getting ridiculous. Those feats might be impressive in vacuum just not in comparison to what I already presented for Sly.
Everything I said about the AP gap is reasonable, Sly scales to or above people who tank the feat, so Robin's AP advantage isn't that high.
Actually yeah, Training under Batman isn't that impressive here, what does Teen Titan Batman have that is Inpressive.
Tameraneans being tough since they are children? The same could be said about Sly except he grew up in a far more deadly environment (Catachan.) and is far superior better then most of his peers and even both types of Space Marines (again I already brought this up and you practically ignored it.)
"Threatening the planet." Is incredibly vauge and the same could be said about Sly, except he can handle these threats alone and with ease. (The command post, Dark Eldar (ancient torture pirates with incredibly advanced technology,) groups of teleporting Assasins, Traitor space marines, (who I already explained what they deal with (and you ignored it.) (to re-iterate, they are often stuck in, and survive, an abstract chaotic hellscape, with out basic laws like time, and such, where nothing makes sense and almost everything can kill you or make you mad, It is also where stuff like Demons and Gods live.)
In comparison to that, fighting people on your own team, that you lead and would be most informed about how they fight, isn't that impressive.
So yeah, those skill feats aren't even impressive compared to why Sly does, sorry buddy.
