I think it is good for you that you liked THAC0 and vancian magic and all that. At some point I liked that, too. But different versions of DnD appeal to different people. That is why some people do not like 4E.
If you want to have a version of the game that appeals to most players (it can never appeal to ALL of them, I don't think), you have to analyse what mechanical elements appeal and do not appeal to players. Because there are very distinguishable forms of taste in gameplay.
You have no problem with that combat example? That is fine. I, however, do. And I have never made the claim that this form of combat is a less valid way to play. I was and am speaking about taste. And about the fact that in my experience, 4E combat does not happen that way. So my claim is that the new edition should offer more than what that combat example has to offer in order to appeal to players of younger editions. 4E combat, in my experience, is different.
To call that "putting somebody in boxes" seems just a little far fetched to me. And it is an aweful way to start a conversation.
Now, this has nothing to do with the fact that I, too, wish for the next edition of DnD to succeed. Actually I am exited about it. But tastes differ and if WotC wants to cater to my style of combat and play, I need something more that "wizard casts a sleep spell and the fight is over" and "let's all go back to 10' poles" (by the way, I think it is very likely the next edition will offer that).
If you would like to talk about that, and whether 4E combat actually IS different from the described example, that is fine with me, after all this a discussion forum. But calling somebody "annoying" is not the form of discussion I am used to and willing to participate in.
