The trick for us FTP types is to understand that you're not going to get everything every time, but if you're patient enough you can get everything sometimes. The last Gambit event was my sometime, when I had really good luck getting slayer cards. I burned everything I had saved up over all the 'nope, uh-uh, not gonna happen' events to get to 51K. Now I have to rebuild my stash over this 'nope' event and several others until I get good slayer cards again. Fortunately, I'm high enough level now that I'll at least clear all 200 areas every time, so it does get better.

For me, EG and shard events are always 'nope.' I can do pretty well in Pero Colo, though.
