The Imperial Clipper is locked to rank.
"The Federal Dropship isn't locked to any rank."
Yes it is. Its locked to Ensign
This is a horse that has beaten to death numerous times. The dropship was made for a purpose that doesn't even exist in the game yet: troop transport. As for T7 and Clipper, I've been bemoaning the absolute superiority of multirole ships for trading in comparison to the pure tradeships in a simliar price region all over the forum for quite some time already. Asp rules supreme over T6, Clipper rules supreme over T7, Anaconda rules supreme over T9.
These comparisons are true in the broadest sense but not if you take cost into account. The T6 costs 6 million fully "A" kitted but the ASP cost 6.1 million stock costing further tens of millions to kit out.
Now its ok for us guys that have the cash and have been playing a while but that to a beginner on hand to mouth trading that is more extra money you can dream of. The T6 is only 850k to buy stock NOT 6 million. It's a cheap buy to aim for from your Hauler and can be upgraded from then a bit at a time as money is earned. Same for the Clipper/ T7 argument it does not stand up. I paid 14 million for mine in a discounted system. Thats a different world to 21 million for the clipper.
