Yeah I think it is better if we talked about this in the metagame discussion thread. In this metagame resisting flying is useless if the pokemon is weak to fighting attacks, just look at Heatran and Tyranitar and how well they wall Tornadus-T/Tornadus-I/Staraptor. Resisting draco meteor is important, no denying that. Arguing that espeon and alakazam are in OU due to their abilities is agreeing with what I said, especially as these are psychic exclusive abilities. In general psychics get great abilities, compared to... fighting for example (notable fighting unique ability is guts). Latios/latias/starmie being better with a mono typing is not true, is it really worth not being pursuit weak (pursuit still 2hkoes) at the cost of not being able to switch into mach punches, close combats, drain punches, etc? You can argue that they are scizor prone all you want but even without the psychic typing they will never break through tyranitar with pursuit or ferrothorn unless they ran specs surf and/or hp fire respectively. Let's not forget that blissey would become a premium latias/latios wall (and chansey/Gastrodon/etc) if they lost psyshock. Heck even amoonguss would be able to check every move in their movepool on every set and then switch out again if its a specs d meteor for +33% (trick gives them black sludge) if they didn't have psyshock... In a nutshell it would be scizor/Tyranitar replaced with blissey/chansey/special walls.
