Yes, most runes are useless, but waiting for oranges, let along oranges with four raises on the same tertiary, is a waste of time.
I use purples as well as oranges, and while I like to see the same tertiary rise at least twice, I don't bet on it. I do, however, keep my purple runes at level 11, so that they stay purple, making it easy for me to know which ones started out orange. Or if the purple is good enough (same tertiary 3x or sometimes 2x), I'll bring it up to 12.
There is something to say for blues and greens though. The advantage of a green is that you know which tertiary will go up the first time. I've used oranges with only one rise in movement speed, so why not use a green with the same? Though I don't follow my own advice there. Like I said, I stick with purples and oranges.
