Not begrudging your interests, but I think this post kind of summarizes why I have never been able to read any western comics.

I like really concrete beginning/end points for fictional media. I like to be able to say "This is book 1, I can start here. This is book 4, it's the last one". I also hate jumping into any series in the middle, even if it is absolutely designed for it. Anytime I have thought about trying to read any western comics (or warhammer on the same note) it just seems like a massive ambigious undertaking.
