PSA: More games are won when all lanes are pushed under their tower
For the most part, this gives your jgler free roam. If he helps top then top/jg can roam mid. If he helps mid then mid/jg can roam bot. If he helps bot then bot can grab FB tower. From there, bot can roam top with jg, 4 man, get top and top splits bot while bot splits top for a bit. From there, game snowballs as your team gets an advantage and if you have a tank, you start diving mid lane while getting picks across the enemy jg.
Food for thought. If you're normally a super aggressive player, try playing pseudo-aggressive and freezing your lane at your tower and see where that leads you. :) If all lanes are shoved up, it kinda puts your jgler in a tough spot. Make it easier on the lass and present an opportunity, even if only one.
