Thats not funny anymore...

I've always hated the store, cause I always get screwed. But if you actually look up the drop rates, it really makes you appreciate it when a mod comes up. Last week I was trying to get an offensive speed triangle for Revan, and when one with +5 speed popped up in the store, I figured might as well. I honest to God figured not a single boost would go to speed. I was pleasantly surprised when it went to +22!!! But even if it didn't, the odds of getting a triangle mod, with the right set bonus, the right primary, and speed secondary is so ridiculously low, that even at +5 it would have been worth it.

I still farm mods though, you do get that occasional good one. And it seems you're just having really bad luck. But I wouldn't go all out on the mod farm.
