Still on the topic of Elesa:
Some people think she's easy, others think otherwise. But, I think we can all agree that she is the hardest GL in this game.
1st Gym: Starter/Dog, Elemental Monkey. Virutally a tutorial in types.
2nd Gym: Easy if you picked up a Red/Blue fighting type. Otherwise, 2nd hardest gym
3rd Gym: Tranquil + Super Luck + Scope Lens + Air Cutter = GG. Pignite too.
4th Gym: Nothing at this point in the game can sweep it without overleveling significantly
5th Gym: Lilligant DESTROYS this gym. I swept it with Maractus for crying out loud... and not just Clay, but the whole gym. Without going to a pokemon center. And I was Lv 31 upon going in. [34 when I came out, and I OHKO'ed EXCADRILL with MARACTUS]
6th Gym: Everything in ChargeStone Cave defeats it. EVERYTHING.
7th Gym: TM Brick Break is in the same town... he's about has hard as Pryce :/
8th Gym: 2nd most difficult Gym if you tackled Aloe with a Red/Blue Fighting type, 3rd otherwise. Could be the hardest gym, but Iris/Drayden's AI, and movesets, severly fail. They Dragon Dance one too many times, and DD + Dragon Tail = WHAT?
In difficulty, IMO, from least to most:
Gym 8/Gym 2
