TL; DR summary (or what I'm gathering)
Cleave is good on high AC low HP targets
Sharpshooter is good while flying and outdoors in general where you can dictate range of engagement (and your party is cool with waiting at your max range)
-5/+10 is good when you have lots of attacks and are either willing to absorb the increase miss rate or you (and maybe party composition) build around finding every accuracy buff you can to mitigate the penalty and/or know the target has low AC
So it seems part of why I've never seen much of an issue (if there is one) is that it takes mid to high levels to really outpace other options (even dual weapon can theoretically add more damage (let's say an extra 11 a turn) depending on the number of attacks, with no penalty to hit) and most of my play either doesn't get that high or doesn't specifically lay down enough support to make it amazing.
I think it is enough of an issue at this point and toworry about it before someone I play with feels it is ruining things is borrowing trouble. Besides, there is a chance it may never hit the home game table at all and my AL characters are 3-4 levels away from the next ASI anyway.
