Game Mechanics: Track on druids

[Amatsu]

So not sure if this has been posted but if not, Playing a half-elf druid, I've pressed Track a good 100s of times now, probably even towards the 1000's mark and I've yet to skill up from 20, dunno if theres an issue where the skillcap is broken or if its just incredibly slow but I figured I'd bring awareness if there is an issue with it. I learned it at trainer at 20 and it went to 20 and hasnt moved since with constant usage.
