Most of the changes we've seen so far for Season 4 of Guild Ball have been rather mild. A little rewording here and there. Homogenized wording here. A small stat change. However, this update is a bit more severe. Ploughman for the Farmer's guild got a pretty hefty overhall in abilities and stats. Have a look for yourself.
From the website:
Yesterday on the blog we revealed the fourth and fifth of our updated Season 4 model cards, Anvil the Noble Patriarch and Sledge the Tempered Steel of the Blacksmith’s Guild. Today we’ll be continuing with our model card reveals with one of the unsung heroes of the Farmer’s Guild; Ploughman, the Honest Labourer.
