Yeah that's what has always annoyed me with Destiny, you don't feel any more powerful whether you're 100 light or 305. As an example, I love the fallen vs cabal battle that breaks out in the EDZ starting area, but now that I'm light 290, I feel like I'm no better off than when I was 100. I still die after a few melee hits or shots from orange mobs, and they still are bullet sponges like they were.
Same with strikes, strikes are no easier now I'm 290 than when I started doing them as soon as I finished the campaign
