I can only catch mon at my house when I use incense, and usually get the typical rattate, pidgey etc. But since the last special event, I have gotten a lot of event mon (during that time)! About 4 out of the 6 mon I normally get from incense at the house.
The last batch included sneasel, piloswine (CP 1264, good prestiger), shellder and charmander (plus krabby and rattata).
Definitely worth it!
