The targeting/preview on Blast moves through larger enemies fine, but when you use the ability, a large enemy can stop your movement. This leads to taking a lot of damage when you try to go behind an enemy but end up in front of them. Some enemies' line targeting shows them stopping when they reach you, so something similar should be implemented for Blast (or the issue of being stopped by large enemies should be fixed).
