Dear LAZ;
I gotta say i'm loving this hack, but in all honesty i can't help but feel that some Pokemon's move-sets ought to be revised, I know you don't want to be just like HG/SS, but with a IV gen battle system the III gen moves seem to come short. Something specific for this room would be perfect, albeit i know that would be a lot of work, and you don't necessary want to do it, I'm just pointing out that little thing that has been bothering me.
As an example HootHoot needs to rely on peck (damage 35, and physical) until it learns Confusion as Noctowl at lvl 41, unless you found some decent move (TM/Tutor) which is both Sp.Attack and STABs with him, hoothoot is worth nothing. It's similar with a Phanpi, it doesn't have much running for it at the beginning except Tackle (and this is worst tackle, before revamp, 35/95)
Again those are just examples, and i'm not complaining, just pointing out the only thing that i tough could be done better on this excellent hack.
