I have to say, a lot of times (in miniature games) some people seem to think their own experiences are somehow the only existing reality. Now, this is problematic when making such black and white arguments as peoples experiences are merely perceptions of the reality, instead of true objective or absolute situations which could be measured, thus having some useful information for everybody.
In other words, you mentioning "flipping out" some matches or some other players talking about having "dice down" in other wargames holds very little value. Yes, there is some randomness always, but the key is not to go for a play (big or small) then decide that "I had bad/good luck" based on the outcome, but rather understand what kind of situations you should get yourself into in the first place - given the circumstances on the board, what cards have been flipped, how many cards the opponent has in hands, what other resources one has and so on.. this creates a very complex situation in EVERY GAME even in the seemingly simplest of actions of making a melee attack against your target. People are easily blaming or gratifying their luck on how the situation turned out, but actually luck has very little to do with it. Note I didn't say "nothing", I said very little.
I'm bad at explaining what I mean, but let's say you had a situation where (for example) your Collodi failed to kill the opponent's Guild Guard because of so called "bad flips" and you lost the game because of it. That is not how it works. The problem is why you let a situation develop which decideds the game in few card flips in the first place? One has all the information available to make the best decision for every situation (thanks to pre-measuring and open information on unit profiles), so why one keeps blaming the deck (or dice in some other game)? Because it's easy. People tend to look for easy solutions, and preferably those which release them from the responsibility.
Now, even if you chose the optimal route in every situation (which is insanely complex and hard.. impossible for a human), then you could blame things on the flips entirely, BUT if you still played according to the probabilities of the card deck (and what cards have been flipped, what cards you hold, are soulstones available, is black/red joker still available), you will win more than lose consistently. Just like so many other games, Malifaux is not about a single game.. just like a single game is not about a single flip. It can be, but good players still win more than they lose, so it shouldn't bother anyone too much even if one lucks out in a single game of Malifaux.
We are playing Malifaux, not a single game of Malifaux. Think big.
I have no opinion on how OP or UP the models are, as I simply don't have enough experience with the game.. I just wanted to say something about the so called "luck", because I've heard this a bit too many times in other games too - like WM/H, like MtG etc etc... and the song is always the same. However, the fact is; luck can't be totally removed from these kind of games, but it definitely can be minimized very very far.
