TBH the jungle indicators make some sense

Just don't add them for camps you wouldn't currently have a timer for.

Adding clarity is good, and a map icon reminder will definitely make people try to contest them more and lead to interesting play, but there's no need to give teams free information. If you're not going out of your way to ward them up, you shouldn't suddenly get to know when they're going to respawn.

If they want to encourage people to aggressively ward the enemy jungle, improving the power of the buffs is a much better way to do it than handing the enemy team information they didn't work for.
