I recently heard that applying bandages is a like a channeling spell, it only works while you are channeling and stops if you get interrupted. So this means that if I'm solo'n and apply the bandage to myself (800 health over 8 seconds), if I get hit within that 8 seconds, I won't get the full effect of the bandage (so maybe 100-200 health instead of 800) and won't be able to apply another for a while!
If this is true then that totally changes how I need to use first aid... I'd have to run away or make sure I'm not taking dmg before I apply my bandage.
Can anyone confirm this?
