I came into exo experts disappointed but now I'm using most of the content. It's so good.
The armor passive along with the gallant make for an ADHD speedrun sort of playstyle. Sliding and running with hip fire and only shooting down the sights when you need it point blank.
The bulletstorm is for holding locations and for mowing down groups and does it so well.
The missile pistol is a middle ground between the grenade pistol and ultimatum with the advantage of being able to one shot gunships
The breakthrough is an absolute beast of a mech. Absolutely crushes things. The lumberer also does very well but with the hitbox error with the flamethrower it's not at its full capacity.
The overall look is very retro and I love it. My only problems are:
The lumberer needs its hitbox fixed
The bonded pilot armor is just so random a design for what it is. It's a kitbashed armor. It has no visual signs of being tied to mech pilots
The armor passive really only works well with the light armor, making the other two choices only good for fashion.
Debating if I want to keep bulletstorm or solo silo in my regular loadout
