Lamy 2000 is unexpectedly dry

As you can see in the samples i provided (The top one using Pelikan brilliant black, a pretty dry ink, and the bottom one using Diamine writers Blood, a wet one) my lamy 2000 is not very juicy, and struggles to keep up with my hand quite often. It is not scratchy, but has this strange feeling of needing to be forcefully dragged over the page instead of writing effortlessly, no matter at what angle or rotation i hold it. I would love to know if this is a common or even expected thing, and what i could and should do to combat it.
