The Breadcrumb Technique ™
So... I'd thought I will ™ this technique and once it is approved by the U.S government I can use the ® symbol instead.. Anyway...
Win a team fight at the enemy's mid inhibitor?? dragon up? baron up? As your bleeding team walks over to either objective you should be placing a bread crumb trail of wards along your path to spot the possible enemy team contest.
Sure you killed the enemy kalista and janna but that riven, sejuani, and brand made it to the fountain and are at full HP home guarding to your weak, clustered team. You need to have vision on them to judge if your team can finish the objective in time or else you risk getting aced.
That is why we use the Bread Crumb Technique™ to place wards as you travel to the objective so you can spot the enemy advance and avoid possible throws. This technique is best preformed by the support as he or she has enough wards... But if teammates actually upgraded their stealth trinket they could do this too. Here is a rough sketch of the Bread Crumb Technique™
