That will let you open then builds.
As for the whole "smash through things quickly, but still survive", I'd probably suggest Bio armor/fire melee. Bio has adaptations that let you be more offensive or defensive, but once you have a solid build done, you can just stay in offensive and just go to town.
Fire melee has 2 PBAoE attacks and a cone, its secondary effect is literally "do more damage"
Alternatively you could go Shield Defense/Electric Melee. Shield is not quite as forgiving as Bio, but it's still a really strong defense set, and Against All Odds increases your damage for each enemy in range. electric melee has a lot of AoE potential as well
