The Sparrow Academy treatment (SPOILERS)

After watching Season 3, am I the only 1 here thinks that The Sparrow Academy got "designed for marketing and promotion so that the fans will watch it and wait for an epic battle between the 2 Academies!" treatment?

Watching the entire season got me no point of them fighting though they should've tried utilizing the Sparrow Academy well, right? Like atleast Klaus should've summon Jayme and Alphonso for distractions at the Episode 10 (since Marcus, Christopher and Fei died because of Kugelblitz).

When Marcus died too early, I felt that the Sparrow Academy is just used for marketing design hahaha!
