Skulls are no fun, easter eggs are limited

I turn on Catch skull while playing on Easy, expecting to be spammed by plasmas from Grunts and Elites alike. It rarely happens (yet I know that it happens very frequently on Legendary).

What the hell is up with this? Even in Reach they’d do this. Have the Covies been nerfed that badly?!

And why are the 8 sniper Elites on Requiem only on Legendary? The Scarab gun was one of the most awesomest easter eggs in Halo and it was accessible on any difficulty!

There’s way too much emphasis on difficulty in this game. I admit, all the cannon fodder requiring only 1 headshot was good but this is just a disappointment. All they do is drop grenades. Why change Catch like this?
