I hope the smaller ships stay relevant during the later levels. I'm personally not that big of a fan of the larger, bulkier ship, it just feels a bit off and not 'runescapey' to be able to control such a large entity...
Also, while I of course don't oppose group content, I like it to be as natural as possible (I want to play the game, not spend time looking for a group). I would like to see solo leveling to stay as close to group exp rates as possible (unlike dg in rs3 where you can get far better exp rates with a decent group). Groups should be about having fun with friends.
Yeah we've discussed the importance that group play is not clearly the best way to train Sailing and so on. Perhaps its something you can do with sailing rather than a training method too. All to work out still but we're conscious of this.
