I hope I won't be flame broiled for this one.
I've been looking at the math behind these three ranger powers for a while, and however I look at it, the expected damage from Twin Strike beats the other two in just about every scenario. So I started messing with different bonuses for Careful attack, and different penalties for twin strike. I think I found the sweet spot to be the following: Careful Attack gains +3 bonus instead of +2, Twin Strike suffers -2 penalty.
I'll attach an excel sheet if you want to examine my findings. They are a bit messy, I was more experimenting than trying to prove a point.
Basically with this configuration, if the attack rolls needed are typically somewhere between 8 and 17 (17 is probably a bit high but go with it for now), there is a fairly even distribution of best approaches for each at will power, against normal opponents, against quarries, and against minions. I've tried -1 and -3 for twin strike, -1 was still yielding results that were too good, and -3 put it below par on everything. For careful attack, I tried +2 and +4, and again +2 comes out weak except when you need very high rolls, and +4 becomes overpowering.
Also with the +3/-2, the expected damage is rather close between all attack powers, so it becomes more of a tactical decission, instead of a mathematical decission to make.
The math will change a bit at paragon levels, but it shouldn't be too different since both the plusses to damage will increase, as well as the hunter's quarry damage. This is of course conjecture, and not based on actual calculations.
What I'd like to hear is if you would still be willing to grab Twin Strike as an at will power if there was a -2 penalty, or if you would consider Careful Attack more seriously if the bonus was +3.
