TL/DR New toons = Lotsa benjamins.... I'm ok with frequent free characters
Gear farming is very profitable for the boss. the top percent of highest paying customers (responsible for like 70% of the overall revenue) WILL maxx out their toons. Its like a crazy collecting game where dinero is no object. Because they feel the need to have a maxxity maxxed roster, they will buy the packs and buy the gear.
Sooo, New toons = Lotsa benjamins.
Maybe it has nothing to do with getting a bump in financials, but more of a marketing strategy because something big is about happen in REBELS that will attract a lot of new fans/customers? Who knows... All i know is that I'm happy with my free characters (ten away from all unlocked).
Guessing that well be getting a ton of darksiders come this dec with ep VIII. The second movie is always darker right? fingers crossed for knights of ren
