Normal content is simply too easy, and unlike most I do actually view this as a problem. A problem thats very difficult to solve because this game does not teach you how to play it in any regard, so raising the difficulty is a hard thing to do because the game has a lot of catch up to do in order to expect more of its playerbase. Which is probably why SE doesn't view this as a real concern.

I honestly cant even remember if this game explains the concept of global cooldowns or weaving to you.
