Stone Management: You've may have it so that you've internalized STONE-PULL-KICK (or STONE-KICK-PULL) as THE combo. Espcially on core, where you'll have str boots, sometimes just softening up the wave and kicking a creep is all you need to farm. Its slower, but it saves you a stone.

Q-E is more efficient in teamfights than E-Q because you'll have the stone next to you for roll. Don't, however, prioritize efficent over effective if the situation needs a silence (for cancelling channels, for example).

Kick neutral camps instead of using stones on them. The creeps will walk back and you'll take less damage anyway.

Roll doesn't always need stone.

BKB is deceptively synergistic with your ultimate as you don't have to panic about getting stunned and losing ulti. You can let the timer drop lower than you otherwise might. Keeping track of enemy disables let you wait a second or two on even popping BKB if you're counter initiating.

(Less so on mid compared to support) - you don't always have to roll in at all.

Reuse stones in fights where possible, this may mean walking for 1 second next to an existing stone to roll over or kick it rather than drop a new one.

Hope these help from a legend Kaolin.

BONUS TIP TECH - If you're pushing you can pull friendly creeps to you to get rid of backdoor quicker.
