Excessive events fired when editing pulls, causing a stutter

[Wotuu]

The more enemies + spells you have attached, the longer the stutter. This is related to the killzone saving, then when its data is returned from the server, for every enemy and spell the killzone is "changed". This causes enemy add/remove events to be sent in succession, causing a UI refresh every single time. This UI refresh should only happen once in this case.
