while this guy with 5 HP methodically kicked me with carrots

That was a moron, I've seen a couple like that too. Now I'd "abuse" carrots on the mill in 2018, what an impact.

Also, I was surprised by the strong growth in the number of Dasha decks and "chimeric" runes. Are the guys just testing decks after the nerf, or are they really that good? On my decks, it seemed that it's easier for them to win than for "garbage," even if it's nerfed.

Probably they "counter" the new dragon. The internet says that overpowered followers like Dasha and Wengoblad knock out the crap from Rovan before he has time to ramp up, put out neutral creatures, and play high-cost removal spells.
