Let's start complaining xD [or not ]. ( ofc its my opinion.. )
1) Pidgeot - rly? IMO u should check it once again. Still is the worst bird and noone is using it.
2) Meganium - ok, Natural Gift and Flower Shiled as a passive are a big help but removing Synthesis is a bad decission. I will suggest adding again Synhtesis instead Aromatherapy and remove Shield couse it would be little OP. Or let Aromatherapy heal itself 30% or more by one time like 1000 and 5x instead 800 and 3x.
3) Sableye - Detect almost the most useful move in pvp and in exp zone and it has been removed. Maybe it was too OP but removing prot isn't a solution. If u can, look on it again and change once again it in other way than removing protection move.
4) Gengar - only one move Nighmtare/Dream Eater, I wrote about it. Its VERY HARD to use them both on one time when Hypnosis is working. Instead one of them atleast Ghost Wind.
5) Magmortar - it isn't a compaining, more a point of attention. It has Smokescreen at moveset and Brick Break as a TM. Raissa once said pokes wont have 2 moves broke reflect ( when from someone Smoke has been removed ). Only change Smoke for any bad fire atk, couse Magmortar looks nice.
6) Venusaur - it's in half Toxic pokemon. Why u don't want add for it Poison Gas a TM. Venusaur is forgotten pokemon, some of players use it but in Cloned Version. For me its still bad.
7) Espeon - come back Boombrust. It was one useful attack against dark pokemons ;3
#edit once more: its sadly about not possibility putting ref + sky att for example.
Venusaur has Poison/Grass type, but it is mainly a grass pokemon. Even according to bulbapedia you may notice it doesn't learn many poison moves.
Meganium got more hp + another heal in exchange, I honestly think it's totally fine. I guess you should try it out few times before making a complaint.
