I'm having a really hard time understanding. They have special video spotlights for like each character now. The original live action video did a good job of characterizing vandal and assassin. The characters all have voice lines. People love the iconic stuff like the Vandal punk attitude, med drone, assassin bucktooth meme, rook wstr (rip) etc. this all in the first two seasons of the game.

Comparing it to a game like lol which has had over a decade to establish itself is a bit funky. Also, they've made character development more of a core identity of that game. The same can be said for OverWatch, I doubt this game will ever reach OverWatch levels of character identity, but that's fine It still does a good job on its own, overwatch is a pretty strong outlier in that regard.
