I certainly do!
Vines are more threatening if they can become Tanglevine after they've hindered something.
The vines do seem like they're kinda slow, unless there are other ways to put them down. I don't yet see Druid's Agro's potential. The fastest way I can see to drop a vine on your opponent's starting zone is to run the Druid there on turn 3, but that's not really the point of the ability.
Defensively, maybe they'll be better? They seem a bit like Outposts. The board isn't really large enough to make them useful?
The Warlord tried to encourage building a fort, and now the druid is trying to encourage building a forest, and I just kinda wonder if that's all so much playing Sim City while the other guy is preparing for war.
Mechanical Engineers build weapons, Civil Engineers build targets.
