Considering the ease of jumping with capitals and bridges and what have you, having the clone jump feature limited to 24 hours feels somewhat outdated with the current state of New Eden.

Some random thoughts on this that I never bothered to flesh out.

It restricts accessibility of PVP, not talking about people that are unwilling to jump out of their precious +5 learning skills but those that fly a variety of ships and might be in their frigate set and get a CTA to do a pos bash with the chance of podding, then next day be asked to go on a BC roam. While you can say 'just deal with it',

I think the modern game features more diversity of activity for each player and being able to at least react to each evenings fleet ops (or even personal goals) with say, a 18 hour limit rather than 24, so you have some flexibility.

There is no reason to cater to people that just want to jump back into +5's at will but easing up a bit encourages more PVP... also useful for people involved in a mix of industry and pvp. In fact it is in this area that it is more critical. Who wants to go pvp with mining foreman links etc?

Lowering the timer enables more activity and doesn't just mean insta jumping across the universe any more than it does as it currently exists.

Just remove learning implants, and there wouldn't be the need for a "learning clone" to swap between every other day. It's dumb anyhow.
