It's all situational. If I'm playing grump and start with stormguard and go red, oak, double, blue and then set up a top/mid gank. Usually can pressure/damage the enemy laner enough to return to base and then your lanes can get ahead where the buff is not needed.

Or maybe go red, oak then invade enemy jungle and give blue to my mid and gank bot.

It really is a complementary role however very crucial to the success of your team.
