First post here, so please be patient.
My current party (and first attempt at the druid) is Fighter/Wizard/Druid. We just finished the third scenario of the adventure pack 1 after completing adventure B.
Here's my deck currently: 4x Blessing of the Gods, Dog, Saber-Toothed Tiger, Crow, Detect Magic, Cure (2), Find Traps, Augury, Detect Evil, Token of Remembrance, Holy Candle. I have previously turned down a Toad (which I think was a mistake), and three other excellent allies since I felt I needed to keep animal allies at all cost. I also turned down inflict at one point because it seemed awful (maybe I misread it). I have not had the chance to get Holy Light.
It may be worth noting that I have played in three other parties as a fighter, a cleric (who I think is amazing), and a sorcerer (who I love). My sorcerer is currently on adventure pack 4, so I have some familiarity with the game mechanics coming up for my druid.
Here's her highlights... Obviously my druid is good for wisdom checks, particularly survival checks, which makes her quite good at closing locations, acquiring blessings, avoiding certain combat penalties, and telling stories to scare children into being good. Survival and knowledge seem to be two of the least-used skills, however, so that's one minor problem. d8 Charisma makes her capable at acquiring allies, but neither the wizard nor the fighter are particularly bad at that. Her Cure spells are quite handy, but nothing really special. Her other spells help her stay out of trouble or speed up her explorations, which is okay. Her discarding ability makes her decent at any dexterity or strength check, but not good enough to matter (more on that later), and her reveal ability is clearly her best asset, adding 1d4 to any of her checks, making her mediocre at almost everything.
Here's the big problem - being mediocre at everything means failing at almost every combat and barrier and only picking up things that others could have gotten anyway. Usually, she will have an animal ally in her hand, so I will assume a 1d4 added to everything for this analysis (although in reality, she takes so much damage that she often loses her allies). Her combat is almost always 1d10+1d4 for an average combat roll of 5.5+2.5 or an unimpressive 8. 8 is not enough to kill much of anything, so you will fail at combat, discarding a card in the process, most of the time unless you discard a second card which is a blessing for an average roll of 13.5, which will usually be successful (but most characters are successful when they use a blessing). Dexterity checks for traps and the like give the same result - an average of 8 unless you bless it, which is usually failure. What is really terrible about the druid, however, is that she doesn't get better at combat!!!! While the other characters I have played can add skill points to a primary stat that increases there combat proficiency, the druid cannot improve - she adds skill points to Wisdom which generally means improving her ability to recharge her questionable spells and that is all! If I reach adventure 4 like my sorcerer, I will still have an average unblessed combat roll of 8!!! Sure I will have better spell for some combats, but that just makes my discard ability even less relevant.
For comparison, look at the wizard in my party. Yes, I know he gets no blessings, so rarely gets to explore more than once (I, on the other hand, have to hold my blessings for combat, so I fail to see the advantage here). We have packed him almost full of combat spells, so he almost always attacks for 1d12+2d4+4 (we have had two skill upgrades), for a typical attack valut of 6.5+2.5+4 or 13 - more than 50% higher. Plus, he almost always recharges his spell, sometimes draws a free spell when casting, and sometimes gets free explores - and remember this is without having to discard!
Our fighter, when using a simple longsword without discard gets 1d10+1d8+5 for 5.5+4.5+5 or 15 - almost twice my score, plus his ability gives him an additional 1d6 quite often for the price of recharging his weapon. Yeah, he is slow because of his small hand size, I get that.
So, I am terrible at combat, not good enough at dexterity to matter (average of 8, remember), can cure occasionally (although I often lose cure to damage or fail to recharge since I need a 6 on d10), and am decent at other stuff like getting items or allies. Doesn't the druid seem absurdly under-powered to you since almost all scenarios require some tough combat? I'd really like some analysis or advice to improve here, since I can't find a way out!
