Increased minion spawn & Old gold start time
MINIONS HAVE SPAWNED Minions spawn at 1:30 ⇒ 1:15 MONSTERS HAVE AWOKEN Jungle camps spawn at 1:55 ⇒ 1:40
The above info is taken from the patch 5.22 notes. Pretty cool, not just standing around for 2 minutes, however, I noticed that the gold per second (which was increased as seen here - 9.5 gold per 5 seconds ⇒ 10.2 gold per 5 seconds) Still starts at 2 minutes. Usually (using mid as an example) you've last hit about 3 minions before you start passively gaining gold with the new spawn times.
Didn't know if Riot has realized this and it is intentionally or not, just thought if it wasn't, I'd bring it to light! =D
EDIT: So a friend of mine pointed out that passive gold generation did start at 1:30 before with the spawn of minions (linked me a video and this is proven) However, in the patch notes Riot doesn't mention pushing the start of passive gold generation back to two minutes <.< So potential bug or a mess up in patch notes. Idk. Either way still something I wanted to point out
