FWIW, I am in Buzz's game, and while I agree with him that our group is not tactical to that extreme, even in our group, you are better as a combat specialist than as a social or sneaky character, because opposed checks and modifiers impact skill-usage *much* more often than terrain/weather/etc. affect combat ability. For instance, my ninja has a great Bluff check. But, his results are always modified by "believability". Now, that might be a reasonable modifier to apply (just as the noise, frequency, etc. might be valid against Hide and/or Move Silently). But, in practice it means that his very high Bluff nearly always fails, while his melee buddy continues to hit up a storm! So, the indirect lesson is: do not play a skillful character, instead just blow stuff up real good. Bummer, really.
Again, if *everybody* is affected by external factors it would all balance out. But, in my experience that is generally not the case. I suspect that might impact Buzz's perspective, where perhaps both frankthedm and E-B have more balanced game environmentals. What do y'all think?
