Exp Progression a Bit Slower Than Usual?

[Cen]

At level 1, kill even cons
At level 2, kill fire beetles and decaying skeletons only
At level 3, focus on fire beetles or other level 2's
At level 4, focus on any potential level 3-4 mobs like large bats, and fill it in with fire beetles.

Don't stick to only level 1's at level 2-4 thats where people don't think of the experience formula per level they are too focused on the con color
