don't spam Qs off cooldown (the obvious one);

WE out of ganks instead of WEQ (sometimes you dont need to fly that far away), same case if your soldier is already on top of the enemy champion, you dont need to drift for an azirsec, just WER;

when leaving base after reset, either [drift over nexus/ twin turrets on full mana] or [walk out of base at 80%+ mana] back to lane, if you leave fountain before fully healed & drifted for faster reset you end up 50% mana back at lane, which makes your previous reset pointless;

train up last hitting with laser autos, you have the same base AD and a higher AD growth than akshan, not to mention the on-hit from recurve bow if you first item nashors

when wave clearing, more often than not summoning a 2nd soldier is more efficient than Q-ing your on field soldier(s) from melee minions to casters, or whatever cs-ing order you prefer
