Have a bard, cast faerie fire, bless, reckless attack, ...
This feels odd ...
Advantages from Faerie Fire and Reckless Attack dont stack ... no?[/quote]
Of course not
I meant that there are many ways to get advantage or other ways to increase your hit chance, which offsets the -5 penalty of GWM and massively increases the damage. In both 5e and BG3, the builds with the highest consistent damage will all use GWM.
Once the full game comes out, the meta striker build will be an archer of some kind, likely Battlemaster, using Sharpshooter and Xbow master. Sharpshooter is better than GWM, because the archery fighting style gives you +2 to hit, and you benefit from high ground with another +2. That alone basically cancels the -5, before you even add bless, bardic inspiration, advantage and so on. So you can hit reliably and do ridiculous damage.
Bards especially combo well with Battlemasters, because of bardic inspiration, many important spells (for example faerie fire), but also the additional short rest, so you can use your maneuvers much more often.
A hasted Battlemaster on lv 11 can do 9 attacks (10 with xbow master), that is 90 additional damage alone from sharpshooter, before your do any damage normally. A longbow deals 1d8+5=9.5, so double that basically. With enough buffs, you will hit most of your shots. And that is before maneuvers, any magic items, +x weapons, any other class features or dipping.
And of course, it is easy to set up guaranteed crits in this game with tashas hideous laughter etc. So double the damage dice (including superiority dice) again
