To me D&D isn't all about the combat, but when combat occurs I like it to be consistent and plausible (not a physics engine however). So insta-mundane healing creates a problem for me.
Exactly. You pick and choose which parts of combat to consider consistent and plausible and which parts to consider inconsistent and implausible. Which is absolutely your right. If it works for you, you play the game, if it doesn't, you don't.
I just don't think you can blame Wizards for creating a game that has these supposed inconsistencies and implausibilities, which some folks in these threads seemingly have been prone to do. As though they were all set to play 'Dungeons & Dragons 4E', but now they can't because WotC had the gall to put in these rules they don't like. If you don't want to play 4E, no big deal. No skin off anyone's nose. But some folks come across as genuinely offended that they can't play 4E because WotC somehow screwed everything up.
Maybe I'm just reading way too much into the postings here. Could be. However based upon the vitriol many people seem to spew towards Wizards for ALL MANNER of reasons indicates to me that I probably ain't too far off. And that's what just boggles my mind... seemingly being actually upset that the game now includes rules that they just don't like.
EDIT: And that's where a lot of posts like mine are coming from. Trying to point out that perhaps that anger is a bit misplaced, because inconsistency and implausiblilty can be found everywhere within the game.
