This hack is really fun. It actually make pokemon challenging and interesting.
I have Furret, Liepard, Primeape, Gardevoir and Shellder as my team.
The stats boost gives so much life to lost and forgotten pokemon. Sometimes it's just as seeing new pokemon. You got to learn each pokemon from point zero.
I do think there is still place for improvement from what I'v seen till now. Furret is a good example: though it has some stat upgrades on the speed and attack, it could really use an improvement on the ability department, to have something even slightly more useful then keen eye and frisk. I'm not talking about sheer force or abilities that doesn't fit the pokemon theme, but Scrappy, Super Luck, Simple, Quick Feet, Pickpocket, Adaptability, Limber... I dunno...
Oh, and what about Slam? Most of the pokemon learn it in a part in the game where you already got Strength. Same move - 100 accuracy instead of 75 (!). I would say, for that low accuracy it should have power of 100.
burgh wasn't a problem for me, for some reason... Primeape fire punch, boosted by Furret's helping hands, just 1HKOed every single bug pokemon, and Scolipede's try at megahorn missed.
Lenora, from the other hand, was challenge. double intimidate on the start of the battle is harsh (though it was to my advantage since my Mankey has defiant) and her retaliate pokemon hit quick and hard. I won mainly because I took advantage of her Herdier's tendency to stick to helping hands and not attack each turn - focusing my attacks on the other poke.
