I am in kind of an interesting position, as I just started playing Malifaux in June. My local group is playing 1.5 until the rules officially come out, so that is what I have been learning, but I have also been trying to look at the 2E rules as well. On the whole, I like the changes I am seeing. I have been learning the game with a Lilith crew and enjoying it very much. Her 2E version looks fun, and I am definitely excited to try her soon.
However, last week I had my first game playing Colette and just fell in love. Yes she was incredibly complex for a very new player, but she was so much fun it didn't matter. Now, because of that experience, I find myself a little nervous about 2E, for the simple reason that her 2E version is an unknown quantity.
Can I wait for her and try other masters in the meantime? Of course. I am looking forward to getting a new Rasputina crew when she comes out in plastic and will learn 2E with her. But I will still be anxiously awaiting the return of Colette.
So, long story short, while i am very excited about 2E, I now have a better understanding of those who have fears about models not yet seen and regrets about model changes they don't like.
