First, thanks in advance for any help offered!
This is my first post on these boards so I suppose it's my introduction as well as my first question. Briefly, I have been a casual MTG player for years and an active PC gamer as well. Recently my wife and I have gotten into LCG's and tabletop gaming and have been enjoying it immensely. I have never posted on here before because, frankly I didn't need to. I just used the site as a database for Call of Cthulhu. My wife recently picked up LOTR and we spent a few days reading the rules, on youtube with "Watch it played", playing some trial rounds etc so we had at least a decent grasp of the rules before we started.
We have played 3 games so far (I have played one solo game) and we have yet to be successful at the first quest. Go ahead and laugh it up

What I need help with is some general tactics and advice for the game. My MTG tactics have let me down badly here, the most obvious example being that defending requires an exhaust. This throws me off tremendously and I am still getting used to it. In all games played we've been using the Leadership and Spirit decks from the core set. We do have some adventure packs, but I'd like to do the core set with just the cards it came with if possible. We also use Shadow cards but honestly those haven't really been what's causing us trouble.I know that without me giving a long rundown of our game it isn't possible for personalized help, but here are some of the general issues we're facing.
-- Being overrun by enemies. If more than 1 or 2 enemies comes out it starts to becoming overwhelming quickly. My wife is primarily using most of her heroes for their willpower in questing and leaving one behind as a defender (the one with 2 defense), they aren't much good at combat anyway so I don't try to advise her otherwise. I usually do the Aragorn/Theoden trick for questing and so have Aragorn and Gloin left over. The first turn isn't usually an issue, I block a spider or something and deal it 2 or 3 damage with Aragorn, and she blocks the attack but doesn't have anything to attack back with. The problem now is...Aragorn doesn't kill much with one shot. So usually the first turn ends with one or two enemies being injured but not dead. Then the next turn starts....and 1 or 2 more enemies come out. Etc etc etc. Allys are being used as blockers and dying as quickly as they are called out, and it seems like an unending tide. This is primarily what we have run into that has ended our games is being overrun by enemies we cannot kill fast enough.
--Using up cards too fast. This is heavily related to the enemy issue, as we seem to have to use up everything we have in our hands just to keep treading water on the second and third turns. Turns 4-6 are when things usually begin to go very badly because we have run out of tricks and now we have a bunch of injured heroes which we cannot use to quest because we are scrambling to keep them as defenders.
I fear we are missing a key concept about this game because it so far seems very heavily stacked against us. You can't leave enemies undefended as they just slam your heroes with full damage. So you can't just quest with everyone, but without questing your threat rises making you more of a target! We almost never have anyone left to attack and when we do, they usually do 2 or 3 damage which isn't enough to kill anything! So we're caught in this cycle of misery and pain

I will cut it off here, even though I have many many more things to ask/discuss, as I have probably already put everyone to sleep with my newbie problems. I am looking forward to participating on these forums in the future and I am excited to take any advice offered and put it to good use learning to conquer this very challenging, but addicting game! In the meantime I will be doing my own homework by browsing old threads with similar themes.
