You can take them down fast because you are a higher level than them. If I'm 34, I fully expect to be able to destroy a level 28 strike boss. I thought that's the whole point in levelling up our characters? So enemies are easier to kill. It's double standards, if I'm level 22 and a level 28 boss is able to destroy me then it should work vice versa. It's a word Bungie use but obviously don't know the meaning of... BALANCE.
