Regarding PRE-Season Changes / Rift Herald
I believe everything looks fine and good. There are alot of things that we the community could tell you about that would probably end up good for the game, things longstanding that haven't been changed in the past years, but should. Probably a lot of QOL changes, but that's not what this is about.
This is about the Rift Herald, or whatever the name might end up being. The little Baron Jr. that spawns before Baron Nashor.
I think it looks pretty good, but it shouldn't have an Eye on its back. It should look less like Blue Buff and more like a Worm with legs.
The reason i think this is because - imagine that Before every baron spawns at 20 minutes there's actually a little tiny Baron Jr that spawns and Grows with each level. With each level something new grows and eventually at 20 minutes it'll Turn into Baron Nashor. It'd be like a little pokemon Evolving.
The evolutions could look like Kha'zix's Evolutions where there's a little bit of animation with something new being popped out and something else falling away.
That or maybe the Rift Herald could be eaten by Baron Nashor in the spawning animation. Or maybe when the rift herald turns into the baron some kind of ritual happens with the Moon and he is transformed into baron. Just a few suggestions. i do think the original idea is better though, and if you do end up making him Baron Jr Could you please NOT name him "The Rift Herald" it just sounds powerless. its as if you're trying to make a strong name for yourself when you have a bad reputation for being small and puny.
