For me it would have to be poffins.
Adding the worthless HM known as DeFog... I mean really? make us have to waste another slot for a worthless move that you only really need maybe 3 times through out the game?
Dive was atleast worthy of something... it opened up new possibilities for exploration and encountering Pokemon under the sea...
Most of the Poketech options were useless. Sure a few came in handy and were convenient, but the coin flipping app? Really? Can someone honestly tell me that they used that on a regular basis?
And yes, poffins are pure evil. </3
wwwhhaaat?
that thing basically made my garchomp !
there's not unlimited trainers in DPPt, and I'm not one of those people who rushes into the Pokemon League with 5 lvl 40 pokemon and a legendary hoping to luck it out, and buys 100 full restores.
Anyway, the Poketch Apps were the most useless, they should have had mini games on the poketch, it was boring and lame
