I loved playing PF 1 Fighters, Elven Curve Blade Human with power-attack. Yelling "FULL POWER-ATTACK!" ever round was great. I just don't see the same excitement here. (It is the same problem I have with 5E)
"cleave" damage usually is bad, and worst at higher levels.
Furious Focus, might be the only power you would use, it's a "you missed try again power". It is actually increases your critical hit chance.
