Talk:Corrosive Projection/@comment-23841937-20131005005939

So fyi, after looking at and proofing the math involved in the comments, the following is a decent summary for the layman to read:

If you're fighting stuff less than level 50 or so, then rifle amp is the way to go.

If you're fighting stuff higher level than level 50, then corrosive projection is the way to go.

My TLDR is at the bottom - Here are some brisk details:

First, it doesn't matter the faction, because the only things that fuck you up with infested are the big poisonous or disrupting tentacle rape-machines that have even more armor than grineer do (base 300 on an ancient vs 50 on a heavy grineer), although chargers do have a notable amount of armor. The other two factions have plenty of armor on their units to go around.

Second, it doesn't matter if you're using an armor-ignoring weapon unless you have no elemental mods (fire/electricity/freeze) attached to it; elemental damage takes a hit from armor independent of whether the base type ignored it. Rifle amp can't compete with the ability to double the majority of your damage output not just on one weapon but all of them. And don't forget - Grineer Commanders, Seekers and Rollers all DO have armor against Serrated Blade damage which comprises many melee attacks.

Last, and most overlooked, this will increase the damage of warframe abilities which don't ignore armor... things like World on Fire or Slash Dash versus Commanders do 50-100% more damage when running just ONE of these cards versus highly-armored units. If your friend(s) are running them, you can count on everyone doing triple to quadruple damage.

TLDR: Rifle amp makes it easier for your primary weapon to kill shit that already dies easily. Corrosive Projection makes it easier for every weapon and ability to kill shit that is a PITA to kill and gives you ouchies, including ancients.
