I agree, however in the type of thread that prompted this one this is clearly not the issue, simply poster's failure (or wilful refusal) to understand english. (For illustration, see threads on milestones, vorpal weapons, cloud of daggers, ad nauseum)If the system has glaring holes and/or contradicts itself, then such a situation calls for intense parsing of the wording of the rules themselves.
I agree again and this was the type of discussion I referred to as helping understanding - My books arrived 3 days ago (thanks Amazon!) so I haven't contributed to the discussions on stealth or skill challenges, but I did read them and I'm aware that those rules are... contentious? problematic? Ah, need handling with care.But in situations like the 4e stealth rules, where there is much less of a clear-cut way to interpret the rules (or at least seems so), that is when intense parsing is called for
