Should beartraps do a % of your life, not static?

[Terran]

It really sucks to be straight-up killed by a beartrap, and I use them a LOT. They're amazingly useful, but what if they did 50% of your current life + slowing, rather than a "Static" 50 damage? They'd still do damage and slow people, but obviously the more health = the more damage. I had someone with 120+ life run through two bear traps and kill me, but I also had someone run into a beartrap at below 50 life and instantly die, which is kinda lame. At least Barnacles give you, say, reaction time. Just a thought, not a complaint or anything.

P.S: I use bear-traps ALL THE TIME so I'm happy no matter what way they are.
