Does support mean DLC, or just weekend challenges? At this point, I have no idea what support means.
For ME3, it meant DLC, patches, weekly detailed balance changes and weekend events.
They promised to "support" this longer than they did ME3, but by this time in ME3's life time, they'd doubled the amount of content available in terms of characters and maps (details here). We also never had repeat challenges during that time period.
The promise of extended support is the only reason I bought the game (I don't care about SP), so it's hard not to feel like I've been scammed.
We can't even get 3 new characters and a new map (which still isn't enough imo) here without any drama.
