I don't think that subskills shouldn't be included in the skill list. Maybe mentioning and linking it in the description of its main skill would be more appropriate?
Skill Overview Page
Thanks for improving this page, User:Karunama (does this create a notification? no idea).
I had kind of forgotten about it. I thought this might be a nice overview for new players in the longer run. However atm we have a bunch of skills listed on the homepage, so I'm not sure where this fits.
I expect over time, we just won't have enough space on the homepage for all the main "parent" articles, at which point maybe we'll remove the list of skill, and link to this page instead, or link to skill category pages (ie. sections of this one) : Trade Skills, Combat Skills, Misc Skill. And then from these overview pages the user can go to the specific skills (besides /wiki <something> supported in game).
ps: On the other hand it could be argued the skills is the bread and butter of this game, and as such it's nice to have them prominently featured on the homepage as they now.
