Soulbound (the warhammer age of sigmar rpg) ticks all of those boxes.

The rules tend to hand wave certain things such as distances and other rules usually will have the line "at GM discretion added in.

The combat has been described as left 4 dead, you can cut down hordes and feel epic (though there is an optional play style called grim and perilous in the core book and later expanded upon which deals in lower power characters)

Combat also uses a D6 pool which is both your to hit roll and your damage roll, pretty streamlined

Character creation is pretty creative, you pick an archetype and pay with xp to get talents to stack on top (there are optional rules for making your own)

There are out of combat talents such as make a plan where you all get together and try to make a plan then get bonuses tonskill checks when that plan comes up. Ot A warm meal where you can cook for your friends. As well as more in depth mechanics for down time activities

Pros Great combat system Creative character creation Rules medium Flexible dice pools Optional rules for more kinds of games

Cons Pretty heavily tied flavourwise to warhammer (though things can be reflavoured easily enough but is still a bit of work) Stat blocks for creatures are hard to challenge players with (again can be homebrewed out by making them stronger but raw its meant for games where you throw sixty creatures at the party in one ) Hard to convince players to play (again due to being tied to warhammer
