1) I don't see how having an extra +1 to +3 due to DM discretion is ambiguous.
2) Not true, you can take default array.
3) Well, that's personal, and 4th Ed specific, after DMing 4th Ed for 10 sessions or so, I grew to despise the AEDU format.
4) I love it, no more +37 to hit and such malarkey,
Total, but people stating that certain editions of D&D are adversarial does not sit right, as they weren't, inherently, we make of this (absurd) game what we will...
Cool, I was thinking a Solo dragon could move, claw you, move, claw someone else, move, bite someone, move, breath weapon and/or spell cast, all in the the one turn (and maybe Tail Slap someones's ass as a Reaction).
Oh, and wing buffets.
Well, many of us do, I do not want to be pigeonholed into changing into a vole or what-have-you to be a Druid; encompasses a whole (howl?) lot more than that.
Me too, it's not that your character will never advance in accuracy, he/she just won't go from +3 to +53.
As for +X items, I believe they have stated they will cap at +3, and are completely optional.
