Hey, it's a good thing to do. To use an anecdotal example: I'm someone who also grew up on the Blizzard games spanning from StarCraft to WoW (even more so than Nintendo games). So I would absolutely love to see a Blizzard character and - hot take(ish?) - prefer them over Crash (even as I'd be fully okay with Crash). Then again, I had the (mis)fortune of having Wrath of Cortex be my first Crash game, so that's a major reason I suppose.
Also, between Kerrigan, Zeratul and Raynor, I'd honestly prefer Zeratul. Partly because the Protoss are really interesting to work with within the context, partly because Zeratul as a Dark Templar is not only a ninja-esque character. but a ninja-esque character that relies a lot on the Protoss' trademark shielding and can screw around with space-time. Now, slows are already in Smash (Witch Time, Foresight), but I do think that the area can be explored further. Kerrigan could be cool too, as a heavy grappler / commander hybrid character mainly.
One last thing: If you were to choose Illidan, would you mostly pull from his WC3 self or his WoW self? I haven't played beyond Classic WoW, so I couldn't tell between the two.
*While I never expect say the Lost Vikings (because they had the misfortune of predating Blizzard's rapid rise) them getting in as Spirits or cameos at the very least would be nice.
I'm not sure on that honestly. Warframe's Switch release Nov 20 2018 (my 28th birthday coincidentally) - before Ultimate released, mind. So it can't be that.
I don't think there was any event: the
Lotus Spirit was released February 28th last year, some days after WarFrame's
Operation: Orphix Venom event had concluded.
Ownership does not turn out much of anything either. Warframe's devs, Digital Extremes, are mostly-owned by Hong Kong-based game / tech firm Leyou. Now, Leyou was in the news this past year due to both Tencent and Sony expressing interest in acquiring them, but that was after the Lotus Spirit was released. Tencent did close in and secured the acquisition by Dec. 23rd 2020, under one of their subsidiaries.
In short, I'm thinking that the Lotus spirit was added because Sakurai thought it'd be cool and Digital Extremes agreed.
