To be more specific than the above tenno, the event IPS (Impact/Puncture/Slash) mods only add 120% to the stat the weapon already has, so if the weapon's damage balance is less than 75% in the same type as the event IPS mod, then mod will be adding less than +90% damage to the weapon's base, meaning one of the 90% elemental mods will be better.

Beyond that, even IF your weapon is heavily biased towards one damage type, impact generally isn't a great damage type since literally everything that isn't a machine/robot resists it. Puncture, while better than impact, isn't as good as Slash even against armored targets (yeah, even without Corrosive Projection, Slash actually eventually outscales Puncture against high armor/high health enemies [and that's not even counting slash status procs, which, despite what a bunch of people seem to think, are based off of the weapon's listed damage after crit/body multipliers, not the damage dealt to the target]) so the only weapons I'd even consider IPS mods on are the ones that do >75% slash damage, AKA the Dread and a few others.

Sadly, a Slash damage mod doesn't actually effect Slash status proc damage. If it did, you can bet that every Dread user in existence would have one and have it on their Dread.
