A dangerous line in the patch notes for Elise
From the 5.1 Patch notes:
Jungle AI
Read below, there's no good summary here.
First, when we say "leash," we're talking about the moment when a monster camp either loses aggro on its target or switches to a different target (ie: when two champions 'juggle' aggro between them). So if one of those Krugs wiggles between two targets rapidly, you can expect it to hard reset pretty fast. This will have the largest impact on duo-lane partners who like to balance monster damage between them but will also affect long-range junglers who use the camp aggro range reset to take even less damage.GO BACK TO YOUR HOME! Jungle monsters will 'hard' reset after 10 soft leashes ⇒ 5 soft leashes. Refer to the above context when we say "leashes" because it gets a little complicated.
Elise has 2-5 spiderlings that tank jungle mobs for her. If she engages a jungle mob and that jungle mob oneshots all 5 spiderlings, won't it hard reset as soon as it targets her? If the mob is bouncing aggro back and forth between her spiderlings and her, it'll happen even faster.
You literally buffed Elise to help her out in the Jungle in the same patch notes, so you know that she's having trouble.
Was this an unanticipated side effect? Did players test this?
