Yes, the Crossbow Expert + Sharpshooter combo sets you up for a game where:All that being said... I'm still leery of the sharshooter version of the feat.
A 2-handed weapon warrior in 5e sacrifices a lot. He can't use a shield for very very precious AC. He does a bit more damage but when someone uses duelist they almost catch up (*and* can use a shield!). In 3e he got 1.5 strength bonus in extra damage, but he no longer anymore. This feat seems to be a way to compensate for that lack - and as I mentioned, it's less efficient for high base damage warriors anyway.
However, for a ranged warrior most of these considerations are moot. The base damage is lower (so it works better) and the archer sacrifices little - yes there is no shield used, but range is a form of protection too. With dex increasing ranged damage in 5e, an archer can afford to focus on dex and have high to hit, damage *and* AC. So I think the sharpshooter version is stronger than GWM. I don't think it's as good as some people are saying (doubling damage? please) *but* it may be too good nevertheless.
- you can use the full range of your weapon
- you are not disadvantaged in any way by having a foe right up to your face
- you can take the +2 Archery style and still get the equivalence of a Fighting Style.
That +2 can't be matched by a melee fighter. In theory, I guess the reasoning went "the melee fighter gets d12 damage dice, but the archer only gets d8; lets give the archer his +2 on attacks instead". But getting a +2 on attacks is better than a +2 on damage, especially in a game with GWM/SS!
My advice is: drop the Crossbow Expert feat and allow dual wielding with ranged as well as melee weaponry.
Of course, my real advice is: replace the -5/+10 mechanism of GWM with +1 Str and that of Sharpshooter with +1 Dex, or similar. (I still think the CR feat should be removed even if you do this)
