I prefer to avoid GMs who arbitrarily kill players to show how badass they are. Yes, titans are powerful, yes, they should kill everything. but I dislike the mindset of
"they'd best be running away from it lest I just decide to inflict enough damage to kill them. "Oh, you can absorb 50 damage and have 20 wounds? You take 80." "
Yes, you are the GM, we already know you control everything, you don't need to hit us in the faces with your GMpeen.
Also, I take it you all would disallow using that power on a conveyor belt? How about in a starship? No matter where you are, you are moving, hurtling through space at hundreds of miles per hour.
