I'm struggling against more powerful quest end-bosses, mostly because I'm unable to absorb a quick-slotted health potion when I'm close to snuffing it.
Before I post in the bug section, I want to know if this is a common issue.
Essentially, out of combat, with a simple click, whether mouse-bind or keyboard, no problem at all, instant potion.
When I need it in combat though, it's hit or miss. I can mash the key or button for a good 4-5 seconds on the verge of oblivion, and I may or may not get my potion.
