Firstly, I apologise in advance if this is old news, I’m not exactly fast when it comes to noticing these things, sadly. I didn’t really find any information in the announcements either.
Previously, when we complete matches, including story-based ones, there is a random chance of a set of 3 boosts dropping, outside of the ISO/Cover rewards. Right now, I can’t really remember the last time I saw a boost dropping. Has this been removed or did I derp again?
Yes they are, just had a +3 red/yellow ap boost drop a few matches ago in pvp. It’s very rare though. I’m not sure if they lowered the drop rates; it was rare before and still rare now.
