We Don't negotiate with terrorists- G.W.Bush.
Why go halfway with them on this?
I will tell you unless they were a small group of kids or a few devs showcasing tumble as a means of travel because only they know why they were pushing this...no one was "tumbling through quests"
Do you know who does roll around consistently, and I know because we all did it... new players, that's it. The fun wears off fast I assure you.
After the thrill is gone you just tumble when it's needed. And the "problem" if it was ever really a "problem" was something they designed with experimental tumble. Before that the skill did EXACTLY what they made overly and unnecessarily complicated with this new charged Tumble system.
You rolled for a longer time depending on skill and you took a moment to get your balance and to center yourself again..like a second or 2.
But no they had to go further and further with it... now you got a little tumble bar on your already cluttered screen... how cute

If it ain't broke... don't break it...
