Well, my point is that most of the time, Batman shouldn't be getting attacked in the first place, because he's too sneaky to get caught.
I take issue with Batman dodging Omega Beams and defeating gods with chewing gum but I can accept the idea that he's sneaky enough for that kind of being to not notice him, nor should he be all that close. Most of the time. Especially with his colorful, powerful friends distracting the bad guys.
Now, on the occasion where he does have to get into a situation where he's likely to be in a fight with a Despero or a New God or a Zod? Then the armor is fine. No problems with it at all if he occasionally breaks out a suit for a particular mission. The panels you posted where Bruce is on Apokolips and wearing New God armor? Yeah, that's fine with me. I just dont think it should be a regular thing; Batman is typically more important out of the fist fight than he is in it.
As for a "low" high tech suit like the Beyond armor? I honestly question why he doesnt wear something like that all the time. But armor like that isn't going to help him against League level threats. Despero will tear such a suit apart as easily as the kevlar and leather Bruce usually wears.
I do maintain that Nightwing should get himself a suit with "Beyond" like abilities.....but I desperately want to see Nightwing out of the street level stuff and back in the "superhuman" sphere......and that's neither here nor there for this discussion anyway.
