Faster travel form

Hello, fellow druids.
Im leveling druid im at 70. And i cant get my travel form to 100% speed. I learned the 40% travel form at druid trainer,i bought fast traveling at riding trainer (i have even slow flying form). And i still dont have 100%travel form.
I did some druid quest (for bear form, for aquatic form).
Is there any quest for the faster travel form or what am i missing? Thanks!

100% travel form was implemented in Legion, I believe.

Thanks mate! Thats it :)
