Horde has decent classes, but I feel they should be rework to have better options. For starters all classes should have two positive passive abilities and one negative. Also all specific classes have faster reload speeds with their specific weapons (25%).
Soldier- expert of rifles and jack of all trades with everything else.
pros: 15% faster reload speed with all weapons. Stacks with other reload bonuses.
ammo capacity: +15%. Stacks with other bonuses.
con: All fortifications cost 20% more. You’re a soldier not a builder.
Sniper- The silent killer
pros: enemy marked by snipers is marked permanently until enemy is killed.
cloak: when using cover sniper remains cloak.
con: 25% reduction to ammo capacity. Make every shot count.
Heavy- The living tank
pros: 10% damage reduction. Iron fist: do more damage with melee attacks
con: 10% speed reduction. Tanks aren’t known to be fast.
Grenadier- expert of throwing. ??? planter.
pros: carry two types of grenades; increased grenade count.
con: -35% reload speed. Stacks with other bonuses. You’re used to throwing not shooting.
Engineer- Master builder
pros: 15% cost reduction to fortifications; repair fortifications 3x as fast compare to non-engineer.
con: take 10% more damage. You’re a builder not a soldier.
Medic- expert healer
pros/con- no idea. If you got any ideas feel free to post your ideas .
Scout- collector of energy. Unfortunately now that the fabricator auto-collects energy scouts became extinct 
Feel free to post your ideas for passive abilities. Thank you for reading this topic.
