I realize this question comes pretty late, but I'm honestly wondering if folks find it to be the case. I realize there's a pretty heavy XP investment, but if you're able to reliably generate 2 force pips, that first Strength upgrade lets you hit like a Heavy Blaster rifle, while the second seems almost like an "instant win" button. 2 difficulty dice to hit a guy with a speeder bike for 20 damage? Yes please! One more and *pow!* TIE Fightered for 30!
I haven't seen it in live play yet, so I may be way off base. I'm just curious what others have experienced.
