Extend or overlap BIG 10 services

I happened to travel via shivajinagar instead of taking the bus to KBS to reach domlur from sanjay nagar. I reached indian express hoping to get 331-A. It did come but it was already full and around 10 more people got in to the bus. The bus was literally full with just about people managing to find place to stand. On the way I say two BIG-10s which were with more than half their seats unoccupied.  Doesn't it make sense to extend BIG-10 running on arirport road toll indian express or shivajinagar? The Yalahanka BIG-10 seems to be doing good after extending it till shivajinagar. I cannot comment on other BIG-10s since I have never used them.

And I don't think I have to say anything on Blue-line and Orange-line buses. It is an idea which has completely gone wrong.
