Improving Warframe loot: Mods?

[Mimterest]

Want to make Warframe's loot system more interesting? In my opinion, with so few slots, stacking directly damage-inreasing stats is the best option. The best way to make dropped mods more interesting would be to commonly create multi-mods, such as a +11% clip size, +45% max ammo mod. Maybe even letting mods generate that go past the current cap for a stat, with a negative component that appropriately brings the mod in line for a strategic choice, such as +35% damage, -10% fire rate.
