New Player, Rogue Question

[muckduck]

Hi all, never played EQ previously and figured I'd try it out. Around the time EQ was out I was playing NexusTK/Dark Ages, two grindy 2D MMOs with a heavy focus on community since my computer couldn't handle 3D graphics.

Rolled a halfling rogue named Fiosach and had one question: Do I need to put a training point into Hide / Sneak for either to begin to improve? I feel like I cast them often but never seen any improvement. I've been saving most of my points for backstab (level 7 so far).
