I'm frequently playing Adv, and, when I finally decided to change my team, I noticed how much effort we needed to put into our teams.
Before, we had to make sure (almost) everything could be countered somehow. Revenge killing wasn't a valid strategy, since about 80% of the major threats had 100% counters, like Swampert to TTar.
Also, the main thing to consider when building a team was how to break walls. Every physical sweeper had problems taking on the likes of Skarmory, Forretress and even Cloyster. Of course, special sweepers had no chance against Bliss. You could also see some other effective walls in Regirock, Rgice, Registeel, Weezing, etc.
Well, and now in D/P, this is not the case. Teams seem to be so easy to build, as walls are no more an issue and Pokemon that sits there taking hits are invitation for some "Stop it now or lose" threats.
Specialized walls like Skarmory, Forretress and Hippowdon can die from ridiculously powerful physical hits.
Pokemon that where difficult to take down previously, like Articuno, Cloyster, Gyarados and Regice are destroyed by Stealth Rocks and the new overpowered moves, even if they resist it.
While there still have immunities, you can't always bring in your Gengar into Heracross, for example: you still have a good chance of getting killed. If he isn't Choiced, your Gengar will be killed.
Now you know that Heracross' set at the cost of a Pokemon.
This somewhat created an excessive guessing game. It's not prediction; you have no way to know nor predict the opponent's set, a simple item will change everything. This even happens with Pokemon that have about six useful moves, like Garchomp.
My point is: offense was made so powerful in D/P that team building is no longer one of key aspects that divides the newbie from a skilled player.
