Eh we could go this forever and from your post i can see that you prefer the old school Batman before all the craziness, while i personally enjoy accepting more of the crazy things that happened thru Batman's life.
But i'd do like to point out that Poison Ivy is a very very powerful foe to Batman in a supervillain kind of way. She can project herself THROUGH plants, lay seige to buildings by sending roots through their foundations. Break bridges, destroy roads with a snap of a finger almost!
I also would believe the Lazarus Pit is way more magical than just pure chemistry. It heals all the wounds and makes you younger. It also can resurrect the dead but with a very very fatal consquence that Grayson is soon about to learn in 2010. @_@
Just incase some anti-Robin guy or "Robin isnt realistic!!!" guy is reading this post, i'd like to point out something quote sweet from Kevin Smith's Batman: The Widening Gyre.
"But I can read the signs-- in another year or two, Tim'll probably go Nightwing and his departure will bring an end to the Robin era. I'm done dragging children into this life. I used to think it was therapeutic for them-- the way it'd been for me. I was kidding myself. In the future, if I ever feel the need to partner up again, I'll do so with an already well-trained ADULT." - Batman
Remember even tho Bruce is a fictional character, even Batman does mistakes such as recruiting Jason Todd instead of taking the poor lad to therapy. =/ I have to say i do love Tim and Richard alot. Tim because he WANTED to help Batman in fightning crime, and Dick because he's just so well developed from Batman's sidekick to a Teen Titans member.

Damian Wayne is pretty kick-ass too with the new dynamic switching places on whos the grimdark badass and whos the joker of the group.
