Greetings all,
I'll get right to it.
1) Drone Toggle Key - As several people have already mentioned, a drone switching hot key is definitely needed (ex. You could press the r key to toggle your drones, from 1>2>3>1 and so on.
2) Colossus PvP rewards - There are currently no rewards for participating in solo pvp events on Colossus, and therefore not a lot of players participate in the event. I believe a lot more players would show up if they actually had an incentive to go there. As a theoretical example, the rewards could be 3 graviton packs and 5k cryonite for the 3rd place player on the scoreboard, 4 packs and 10k cryonite for 2nd place, 5 packs and 15k for first place, and 1 graviton pack for all other participating players that achieved 5 kills or more.
3) Conquest rewards - Similar to what I pointed out in the Colossus rewards, there isn't enough incentive for individual players to participate in their respective clan's conquests. A clan receives 20 gravitons for winning a conquest, however those gravitons are not distributed evenly among the participants or any of the other clan members (nor should they be). It used to be that clans were required to pay a cryonite fee to participate in a conquest, and the total cryonite paid buy all the clans would be divided up and paid out to all the participating members of the winning clan. While I like the new log-file system, I believe there should be a cryonite reward (free cryonite, not from cryonite that you have to pay to participate with) for all participating members in the conquest (losers and winners). It could be something as small as a 3k reward for each member of the losing clan and a 5k reward for each member of the winning clan, in addition to the 20 gravitons.
4) Reduced PvP Cryonite loss - Several people have already mentioned eliminating cryonite loss from deaths resulting from PvP. I disagree with eliminating all PvP casualties (since that's the risk you take when turning Pirate Mode on), but I do agree it is a bit too much for official PvP events. During conquests and colossus PvP events, I believe there should be a noticeable reduction (50% seems ideal) in the amount of cryonite you lose upon dying.
5) Greater Rewards for bounty - There just doesn't seem to be any reason to hold onto bounty right now, and Pirate mode is only really useful to lower level players for the 5% xp bonus they receive. There's no reward at all for it, and although it's nice to look at the bounty board and be the holder of 30k points, it doesn't really mean anything. Someone could simply come up behind you while you're farming on a ring 4 sirius planet and fire 1 blaster shot to take the entire 30k bounty. Then, they can hold it themselves until...nothing happens. There should be a cryonite or energy reward for the bounty you turn in at the end of the week. For example, if you have 30k bounty at the end of the week, you should receive 30k cryonite or 30k bonus energy (a one to one ratio might be a bit much, but you get the idea). Also, you should not lose all of your bounty upon dying to another player (this would prevent players from losing 30k+ cryonite in rewards just for dying once). And, to prevent players from simply stacking up bounty from low level players and then sitting in orbit for the rest of the week, there could be a bounty-decay feature. For example, your bounty could start to decay at a rate of 1000 points every hour after you have spent more than 36 hours without either killing/dying to another player in PvP. And finally, to reduce the amount of newbie-podding, you should only be able to receive bounty from killing other plays who are in the same system ship as you are (and you will only lose bounty if you are killed by a player in the same system ship as you). If you're in a Gemini ship, you should only be able to win bounty from killing players in Gemini ships or higher, and you should only be able to lose bounty from being killed by players in Gemini ships or lower (note the lower and higher). And there should of course be a limit preventing players from winning bounty by flying gemini ships around with sirius blasters, etc.
In Conclusion:
6) Tau Ceti System - Tau Ceti needs to be completed and released. The system needs to be like the previous systems sol and draconis when it is released, with new story missions, enemies that do not take 50+ shots to kill solo (excluding special enemies from missions, events, harvesters and the like, etc., new standard blueprints (none of the unbalanced long-strong-rapid), and an environment that is challenging, but not completely impossible for solo players. In Sirius, everyone was forced to join a large clan to progress through the game and get better tech (face it, small clans of 5-10 members had no chance). And even in the large clans, it takes a long time to bring down enemies in Sirius, and when you need practically a full squad to hunt 1 blueprint for 1 member, it simply takes too much time (Sad fact- people hate waiting their turn, and there simply isn't enough time for everyone to get what they need). When Sol and Draconis were released, although they were challenging, it was possible with time and effort to get the blueprints yourself and complete many of the missions alone. I'm all for encouraging team-oriented play, but there needs to be a way for players who want to play alone to progress through the game and grow stronger.
