Blue Trinkets: Better for the team in the lead

I've noticed a pattern in the broadcasts of LCS games in the past couple weeks - the team that is in the lead switches entirely to blue trinkets instead of yellow ones, and the commentators express confusion as to why the teams' trinket setups are reversed from what they expected. However, I don't find this surprising at all. The blue trinket at present produces wards that are, as far as the team that is in the lead is concerned, better than yellow trinkets. Long range scouting is a secondary feature of the blue trinket, rather than the primary one.

The current iteration of blue trinkets are pretty bad at dealing with the facecheck situation that they seem like they're designed for - since the vision is completely tied to the ward that gets placed, successfully finding a death brush with a blue trinket only shows your team the trap for a quarter second, after which point you have no idea whether they are staying in that place or moving to another location. That moment of vision can be pretty relevant if the opposing team has actually started Baron, but is only slightly useful otherwise.

What the present blue trinkets positively excel at is not finding where the enemy team is, but where the enemies are NOT. With the ability to place about twice as many wards total as the yellow trinket, and an infinite duration, blue trinket wards are the ultimate tool for vision in areas you already have control over. The team that is in the lead can expect a blue ward in the opponent's jungle to last 5 minutes or more, while a blue ward in their own jungle will often last 20 minutes or more. Using invisibility to keep a ward safe like the yellow trinket does is important to a team that has a hard time defending positions, and not particularly important to the team that primarily protects wards by punishing the enemy for trying to walk into the area at all.

I suspect this is not how Riot wanted the blue trinkets to be used - the LCS commentators' idea of the team that is behind taking blue trinkets to assist in retaking control of the jungle sounds way more intuitive than the current actual use of the blue trinket. My opinion is that the blue trinket should work like the upgraded blue trinket of last season, where directly spotted targets can be seen for a long enough time for the data to matter to a team trying to regain control of their jungle, and the consolation prize ward for not spotting the enemy has a limited duration (certainly not longer than the current yellow trinket duration, and probably shorter).
