Sure, Espeon isn't tough, but that's an exaggeration. It can easily survive most neutral priority and takes resisted moves pretty damn well. I've seen it take less than 50% from my Roopushin's +1 Guts-boosted Mach Punch before.
well dude thats a 40 base power move, I'm not surprised. It takes like 90% from hippowdon's minimum attack earthquake which means it is weak and anything it doesn't resist and has a decent attack stat will probably OHKO. 65 hp/60 def is worse than lucario ffs.
