Hey again! I've been playing through this again the last week or so (attempting a hardcore nuzlocke, which has been a blast actually, even if I've failed 4 times already lmao)
Something I noticed that Combee still seems to have an 87.5% chance to be male, which doesn't evolve? Same with Salandit. At least, no changes on their part are documented anyways. A potential change (in both this and EXWY) could be to make Salandit and Combee 100% female (or maybe flip them to 12.5% male, 87.5% female?). Alternately, could enable both genders to evolve- male Gardevoir and Primarina exist, it wouldn't be that farfetched to have a male Vespiquen or Salazzle tbh. Might go a little bit against their lore, but any of these would be a nice QOL change that'd help get rid of the grind having to search for that rare female to have something actually useful.
Another thing I noticed was that you gave Togetic Fairy Wind at 14, but not Togepi, so it's kinda screwed out of early fairy stab if you don't friendship grind fairly quickly. Friendship is easy enough to grind though, and its fairly feasible to evolve in time to learn Draining Kiss at 27, just wasn't sure if intentional or not.
Last thing I noticed was that Umbreon does not get Foul Play at literally any point in the main portion of the game, as the tutor for it is locked to the battle tree. This severely undercuts it's use, since its attacking stats are subpar at best. Maybe give it as an evo move over Pursuit, or at least as a levelup move (maybe around the mid-30's, since Vullaby's is at 35?)
Great game as always :)
