Yeah that grass event speaks volumes on how little CAGs are discussing it. I was happy to speed through a Jumpluff, as well as get a Meganium (and well on my way to a second one), but that was the extent of my positive experience. The fact that I didn't see a single Tangela during the event is the biggest let down, I was hoping to stock pile those candies for the Gen 4 evolution.
If next month is a strictly fire event, not sure I'd be too excited for it. Fire + Ground may be more interesting if it means a higher rate of Phanpy and Larvitars, as well as for those not in the Geodude / Rhyhorn biomes.
