Seeing how heroes get healed and how vehicles get healed is perfect the way it is ;D Boba Fett didn't die in 10 seconds but flew away and got himself healed and then started attacking me again and flew away. Han Solo somehow got himself badly injured, sent him to the bacta and got healed in 3 seconds. What a way to make heroes annoying ;D Fun fun. I can imagine Obi-Wan getting near death then get healed and be annoying again AT-AT healing within a minute or 2 sure is also realistic. I agree it does drag the battle but its the suspense that brings fear into people at "What the heck is he/she up to"
