Couldn't agree more! There should be a dedicated development section either on here or on the main site, split into 3 sections: Bugs, in test, in development. Each item should have an entry created date, description, current status, and expected live date, along with an area for additional comments e.g. why it has been delayed/withdrawn etc. There should be commitment from someone in the dev team to maintain this (or maybe community managers, as long as the dev team actually provide the updates weekly). Players should be able to prioritise the bug and development entries (perhaps some sort of voting system?) so BB know categorically what matters most to the players. We've been out of beta for a long time, there should not be players having to come on the forum to complain that their generals have been lost in the ether for 60+ days.
I'm also a fan of the concept of crisis quests though experience has taught me that the implementation is often seriously flawed (find x amount of y resource on very long search, early in a time-limited quest chain; balloons (!!!!!!!!!!!!!!!!!!!!!!!!!) (and associated happy hour that favoured certain servers in a cross-server competition!!!!!); overall rewards not proportional to the effort and expense required to get them, that kind of thing). That said, the Halloween and Christmas events were actually pretty enjoyable from where I'm sitting so maybe there's some new blood in the BB development team and the next crisis quest will be more reflective of achievable, enjoyable gameplay.
I would also like to see alternative payment methods for halving geo/explorer search times and instant complete for build queue (coins, beans, star coins, granite, water, a.n.other in-game currency which doesn't exist yet - the possibilities are endless) - yes gem buying pays for development etc but as has already been said... new and old players leaving quickly due to stale gameplay without buying anything is more hurtful to the profit margins.
I haven't hit level 50 yet but should do in the next couple of months so I too am keen on seeing something significant and long-term appearing for top level players. Personally I'm not terribly interested in pvp but inter guild competition as suggested by jollyfog/Dust2Angel or setting off to find, populate and develop a new island with different resources, requirements and adventures seems like a reasonable evolution in the spirit of the game. So many people have suggested it... maybe level 50 and an 'unlock' cost of 100k beans or stalks or star coins or SOMETHING would seem reasonable expenditure to access a whole new world of content. There are loads of players who are enthusiastic and creative in suggesting meaningful improvements but all we're offered are granite pits.
