This suggestion is simple. When you release content, that increases the max level of our characters, update the gear from packs BEFORE you release the world. This way, people can go right on purchasing packs and use the new gear right away, instead of having to wait 6 months before you even update the packs (as a whole). This is a major pain point for those people who buy packs; the gear isnt updated. I think it's safe to say that new worlds take months to create. During that time, how hard would it REALLY be to take a few days and have people working on updating pack gear to those new levels? This way, you get the bonus of adding new levels AND updating packs. people will go bananas in test realm buying gear to see the new stats and if it's worth it. You'd be driving demand much better by saying:
"Hey, check out this new world, character levels, gardening/fishing levels and spells, and new pack levels".
