Buffs give 100 less experience (33%) despite being considerably harder
Reading the patch notes, this looks like a terrible mistake:
On giving buffs to allies: "Junglers have more control over how much experience/gold they give up..."
Buff: xp: 260 -> 100 gold: 60 -> 42
small monsters: xp: 20 -> 50 gold: 7 -> 22
Doing the math for you (2 small monsters per buff), that's a previous total of 300xp and 74 gold for the camp. The new total is 200xp and 86 gold.
That's 100 less experience (or 33%) for a camp which is now stronger, spawns later, and gives a shorter buff.
How in the hell is this balanced?
Honestly, I think the xp was meant to balance equally, and Riot forgot to carry a 1 and ended up off by 100. The buff should give 200xp rather than 100, shouldn't it?
