I have two main problems with the current community goal and the "blockade":
1) The financial rewards for the community goal are hilariously bad. Trading copper at 150cr/ton profit is poor when you compare it with the 1000cr/ton profit you'd get trading more expensive goods. Coupled with the fact that most people are going to make ~15,000cr on top of that, and get a discount on a ship they're never likely to buy or use (Fed Dropship).
2) Those people who want to dominate and potentially kill players in trader ships are unlikely to have the roles reversed. I would be happy to attempt a blockade run if I thought that the tables could be turned at a later date. If there was a similar 'build an empire capital ship' community event, I doubt the PVP groups would bother playing, let alone participating while in the weaker vessels they choose to prey on.
I am directly losing out on regular financial advancement in ED for every single moment I participate in the community goal. For the blockade, they get what they want, which is an encounter where they either force someone to drop their cargo, or they get to kill another player.
I am given no bonus reward for managing to break through, so my options are either A) Make a minor and relatively unprofitable anonymous contribution to a mass community goal, B) I'm forced to drop my cargo and definitely make my time wasted, or C) Get damaged or destroyed at the hands of players with combat-optimised ships, where I have little or no chance for an equal footing and fair fight.
And please don't say Wings will "fix" this issue, as it just raises the entire sea level for this scenario. Blockade enforcers will be in Wings, as would blockade runners. We've gone from a 1v1 scenario to a 4v4 one. This is providing that you can get 4 blockade runners, as they are the ones with the largest amount of time wasted in performing escort duty in locations where it's entirely unnecessary, and their role only becomes useful when you actually reach the target dropoff point.
