Just an idea...
Make Bolt Escape an AE target spell that requires a left mouse click placement to cast.
This would cut down on its spammability while also giving more utility to intelligent sorcs who aren't just trying to run for the hills. A smart sorc with enough skill and reflex could teleport to a strategic position to avoid damage, while a bad player just mindlessly spamming it would have to adjust their cursor and place the targeted area for multiple casts.
Rewards skill with more utility and cuts down on spam.
What are your guys' thoughts?
