I just think people make way too much of this issue. For me personally, it helps to keep the game fresh and adds replayability factor if things don't happen exactly like they did the previous 10 times I ran through the game. If I fail a dice roll, I just find another way or I write off an opportunity lost. It's not a big deal folks.
The Gith patrol fight wipes my party at level 4 unless I cheese it or go there when I have done everything else in EA, so I reroll to get the deception check right to make them go away. Sometimes that rerolling takes a dozen tries.
