I'm sure most of you all have had difficulty in Diamond, Pearl, and/or Platinum with the gym leaders and Elite Four. Which gym leader and/or Elite Four member did you have the most difficulty with?

To answer my own question, for the gym leaders I would have to say Fantina in Platinum. She really did improve since Diamond and Pearl.

In gym leader no other than Fatina and in Elite 4 no other than that "Psychic" leader.

Yeah Fatina was bit stronger than before ( that's what i mentioned btw but anyway )

Cynthia. xD

Elite Four were no match for my team but the champion cynthia.I got defeated by her superb garchomp.She is amazingly powerful.

In my opinion, its Fantina and Crasher Wake.Wake's Floatzel is amazingly powerful.

Crasher Wake is the game of left hand If you had taught your Infernape Grassknot.

But its floatzel is so fast that it would use a water type move before your Infernape

NO It only uses Aqua Jet to get hit first but it will take half of Hp.
Even if your Infernape is down,Staraptor can take it easily with Close Combat.

Staraptor at Crasher Wake?? I usually get it at Canalave City gym..

I evolve my Monfernape and Staravia at the solaceon town where there is breeding centre.
Actually I take only two Pokemon or three in Platinum where I took Luxray also.

Same. Well I also love the trio of Infernape, Staraprtor and Luxray.

Then it is solved that is is not difficult to defeat Crasher Wake.

But still. With Infernape,Staravia and Roselia, I managed to defeat Crasher Wake

When you have roselia then what is tension.
