BZZZ wrong. The rough start was 100% the lack of end game. They werent prepared for the speed mmo players rush to end game and didnt have enough prepared for it. This has been discussed in length over the years so I am not sure why you are trying to argue against this fact. The story is the best aspect of the entire game and what everyone talks about. The PvP was fine in most areas the Illum pvp zone was a bit rough though. But general leveling was fine once you got off the starter planet.
The alt experience was great with the linked "family" style approach. And it is P2Win a bit now yes but it wasn't at launch.
