And I know you mentioned increased difficulty, but if I can't beat Burgh with a 34 Combusken, a 27 Marshtomp and a 25 Kirlia, its too hard dammit.
And yes, the other 3 are too weak to even bother having in my team for the battle. They just drag it out 3 more turns or so. Took My Blaziken lv 36 to win, everthing else cept Marshtomp was killed in a single hit. I literally only won because of Blaze Kick, I'd hate to see how anyone who chose a different starter manages to pull it off. The only fire type available is the monkey, unless you find a Torchic in a grass shaking spot. And the only other options ar a Swellow or a high level Golbat. And that's pushing it.
You need to edit the trade in Nacrene City. Petilil for Cottonee. *And now that I've been to Driftveil, check all the trades.
I suggest Roselia for Gloom. Or similar.
Check the other trades too.
*More bad news-
You missed the trainers on rt 16
forgot the fossils in the Relic Castle
Trainer in the Desert Resort- Backpacker Kelsey, his Tailow has no moves- only can use struggle
Trainers and wild PKMN on Rt 17 and rt 18- accessible after beating Rival on rt 107- not edited, surfing is however.
And i suggest making the dawn stone available before rt 10, some people may want to evolve thier Kirlia before the 8th Gym.
Steven, when introduced, still refers to himself as Alder.- Just double check the text refering to changed Characters and Locations. And Pokemon, such as the rival's refering to various PKMN.
*Foongus (assuming Amoongus as well) haven't been replaced.
*Timburr is still wild in the cold storage outside area.
*Is there a reason that the Striaiton Gym Leaders and Clay aren't double battles like the other four so far? And that neither have a team of 6?
*Wellspring cave 2nd floor, Missingo in the water while surfing!
*Desert Resort, when Steven flies away, he reverts to Alder.
