I did a one shot playtest of the four classes released so far, one of each type at 8th level. Everyone enjoyed the session, so I consider that a success. Questions did come up about the Witch's Hex ability. I've seen posts address a few of these issue, but I can't find any mention of one. The Ward Hex does not list a specific range for its use. Neither does the Charm Hex. As an on the spot ruling, I decided that they would have a 30 ft range, similar to the Evil Eye Hex. This would also make them analogous to the Bless and Charm spells, so that seemed OK. This worked in play, but a specific range, 30 ft or touch or whatever, should be listed in the final version.
I have seen concerns about the Evil Eye Hex in other posts. As I interpreted it, Evil Eye does not seem to be limited in how many can be running at once. Also, it didn't seem to limit how many different effects can be Hexed on one creature. As it played out, the Witch used Evil Eye on the Bone Devil that was the main encounter three times in succession, hexing Attack rolls, then Saves, then AC. In each round, she Cackled to ensure that the effects would continue. This was powerful once it was in place, but it did take her three rounds and all her actions to get it going. As the Witch does not get a lot of direct damage, I think that leaving this as is would be OK.
