It's not safety but speed but.... ok. Don't flightpaths offer much the same "safety" option? You fly over terrain, obstacle and mobs just like with freeform flight. You 'trivialize' ground content even worse, don't you, because you can't even voluntarily stop and engage... you're forced to finish the path before you set down.
I would say that flightpath as no better than, and in someway worse, than freeform flight for that very reason.
It's what Bashiok admitted to in a post back in March. The furor that cropped up as a result caused Blizz to edit the post to remove the admission so good luck finding an intact copy... but tons of people saw it and remember it. "Worthless" or not, it is fact.
Just like needing 120 mats to craft and item this xpac instead of only 80 for a similar but less powerful item from last xpac slows us down so... yeah?

Here, here! No mounts of any kind either. No runing... all walking all the time.
And let's remove weapons and gear, potions and food too.
I know! Make The Ironman Challenge the real game... 24/7! Now THAT would be "something completely different!"
