I can assure you that we aren't doing either of those things... paying ourselves crazy salaries or only working 15 hours a week. That said, you underestimate the cost of hosting/bandwidth. Neither is cheap and the game may be 11 years old but it still requires a rack of servers for each shard as well as website and support hosting. Hardware does fail and has to be replaced. we spent a lot of money upgrading components a while back. So, no, its not all money in the bank so to speak.
That said, since we aren't funded by a large company like EA or Activision we don't have them breathing down our neck to make millions under threat of imminent shutdown. We're owned by the folks making the game and so there won't be a shutdown anytime soon so long as people are playing (and paying).
Some feedback on other points:
1) Class changing - This gets tricky when you consider experience. Its not a new request, that's for sure. But it's not something we're ready to do yet either.
2) Mining/Gathering - Istaria is not WoW or other theme-park games. Crafting in any MMO has a time-sink. For Istaria that time-sink is primarily in the gathering step. Crafted items are instantly made once you have the necessary resources. In other MMOs, such as WoW, for example, the time sink is split between finding the resources and making the items. Nodes are relatively rare so you have to hunt them down (as opposed to being in fields like here) and then you have a casting-style bar for making the items. One at a time, as opposed to bulk. Hard to say which is better, though certainly the experience itself may feel quicker in WoW... but it really isn't. That said, we won't be changing that as the system is a fundamental core piece of the game.
3) Combat Speed - This is also another aspect that has been discussed for years. And, as pointed out, it would not be an easy switch and would require TONS of play-testing. No tjust for the speed, but for the monster balance and level speed and so on. All of these things are tied together. 11 years in, probably not a good idea to change them.
Thank you all for your feedback. It is appreciated. Keep it coming!
