I have a huge thing against evolutions that only affect one gender and leave the other practically useless, as Combee and Salandit being female-only evolutions showed. Doesn't help that they had to make the useless males way too common just to make it so hard to get Vespiquen and Salazzle.
Both lines not getting a male evolution was a missed opportunity. Look at how Burmy has a split gender-based evolution path, and while Mothim and Wormadam do suck they are least there and don't leave a certain Burmy gender entirely useless.
