Just some random stuff, I'm not going to quote people because it'd take too long.
Axes on a 'Sin are bad because the only thing axes really have going for them is through using Warrior's Endurance to fuel Cyclone + Whirlwind + Power Attack spam. Sure, you could use crits for energy management, but it wouldn't be as consistent. Plus, the 40 armor-affected damage you get from a crit really is not that great, and armor penetration plus 14-16 Axe Mastery will probably make up for it. And people hardly even run WE Axe in the first place, because it's outclassed by, you guessed it, scythes.
People don't use Farmer's Scythe partly because it is conditional, but mostly because Mystic/Eremites provides a built-in IAS, which is crucial for the slow attack speed of scythes.
That buff looks good, except probably a lot overkill. I have a feeling it's gonna get abused to hell by farming and such, because scythes will definitely be rediculously OP if even half of that stuff is done. Should be interesting...
Zodiac, about 99.5% of the nerfs in PvE have been because they affected people from getting into
farming groups, or just created a broken method of farming. ER has little to no effect on farming, thus under ANet's current PvE balance policy, it's not gonna get a nerf. And besides, it's still a lot more fragile than a regular monk, and like you've said, it does require a decent amount of skill to play. You also hardly ever seen anyone playing an ER, like, ever. If ANet sends a nerf to ER, I'll be damn pissed because there are so many more broken things than that (Panic, daggers, scythes, SPIRITS, soul reaping, DwG, etc. etc.).
If AoHM stops converting to holy damage, and scythes get any kind of buff whatsoever, scythes will easily surpass daggers (if they hadn't already) as being the most broken weapon ever in GW, by a huge margin.
Oh, and when are we getting our 7-hero teams?
