That's sad for you and I sympathise, but it happens a lot. Many groups abandoned D&D when 4E came out.
At the end of the day, this is a fairly narrative system and most gamers who like 'builds' and tactical combat and loads of rules aren't going to like rules-lite, theatre-of-the-mind games.
I think the FFG SW game falls somewhere in the middle in terms of complexity - it has both a lot of mechanics and mini-games, and a lot of -make-it-up narrative moments.
But if you're players aren't going to like the rules, it's best you all acknowledge that and they find something you do like.
Over the years I've cultivated a group of gamers who mesh well with my own style of GMing. I appreciate I'm lucky in that regard.
I doubt anyone here will see it as 'poetic justice' anyway.
I find it amusing and odd that "build" focused players are turned off by FFG.
The engineer part of me is more distracted (or stimulated) by point buy systesm like FFG than class based systems like d20.
They both get my mind churning but point buy systems are typically a lot more complex.
When you're spending XP you've go soooo many more options and combinations and paths to consider. With a class based system you've got a lot fewer paths to take.
