I'm not trying to be rude when I say this.
People who say things similar to this simply do not know how Eureka works.
Before you panic, try and find real information, ask around or google it.
Not to mention; your concern is about content that is designed to take time, something you are poor in, of course you will take longer.
So the natural conclusion is that you need to fit in as much progression as you can in a limited amount of time. Now luckily for you, you can get EXP bombs in the form of NMs (The way everyone else has leveled by the way)
Simply put: You want to spawn an NM, you need to kill its placeholders.
Who are the place holders? Google (And Reddit) to the rescue, thanks to many players testing and figuring it all out~!

Personally I prefer to use the map.
Just kill whatever placeholder monster you can (solo or in a group) until the NM appears, invite the people who inevitably shout for invites and kill it together! BAM! A chunk of Crystals, Lockboxes and an Experience bomb will be your reward! Don't forget to change your element to suit the boss, and don't be afraid to change to Defence if the NM is a bit higher then you are, you'll still get gold if you are in a party.
And this is current and
before the next update, where they will bring in Level sync, a new solo content and sync down everyone's elemental wheel with the NMs lvl
^^)/ So don't feel disheartened people. Eureka is a hunt!
