So even though, you just need to use the skill to keep it 'active', once a week or so, that would be over the top for some people you think?
It is a hardline measure, but my feeling is that it would increase the activity of some people just a little.
- Move them from afk at recall to go mount a horse, or find a tree to woodsing, or manifest a weapon.
- Have people log in to the game at least once a week to do these things, to maintain their character, and as a side effect, see what is happening on the game and perhaps stay a little longer then they would have normally.
Maybe a longer period, like 2 weeks, before it degrades, and have a smaller percentage loss, like between 1 and 4%.
Even so, I don't think using a skill or spell once per week is 'spamming it all of the time' hehe.
But you do make a good point, what ideas could you offer towards a comprimise in this, towards the goal of:
Flushing out unused skills
Having people use skills they don't use that frequently, to become more familiar with them, and perhaps increase their popularity.
