LFHELP,Sign intensity Runes

[DinoBot420]

So i would truly appreciate any great advice or tips on what to do with these runes for armor and weapons, ive kinda been winging it for th elongest time, i enjoy the color it adds to the blade and sure a very small chance to freeze or burn or w/e. but im starting to fill up on them in my storage and in my bags, I was wondering what these intensity ones do really, like can anyone give me a few examples? as of right now i have only uped my axii sign for diallogue purposes,some of the other signs look cool like alternate modes, which im assuming replaces the original for something better? and with these intensitys does that mean they are just abit better?

Any input greatly appreciated, im trying to make some coin off stuff i dont need and clear up space, i also mostly dismantle gear instead of selling it, and looking at the junk stuff that can be dismantled im abit lost because sometimes it says required to finnish a quest, however i dont think i have that quest anymore, or sometimes u need the pelt of a wolf, but sometimes its nice to have the leather from dismantlying,

Agh >.< help plz n ty!

Intensity just amplifies the effect and/or duration of the sign.

Aard intensity increased knockdown power.

Igni intensity increases damage.

Yrden intensity increases slowdown.

Quen intensity increases the amount of damage the shield can take.

Axii intensity increases the duration of the stun.

And alternate signs don't replace the original ones. You can use them both. Once you have the skills, you hold the button to cast alternate versions.
