Not sure how accurate that roster is given that 3 people were apparently flying the Krait...
EDIT: As for the Anaconda and it's magical armour. Sure, it's a bit of an outlier but is it a gamebreaker? I don't think so. It's not like everyone is flying it at the expense of all other ships. Sure it's popular but it's also the only 'big' ship that isn't rank locked so it's going to be popular. I suppose I might be biased as it's my favourite ship (though, it has to be said, not my most flown - Not even in my top 3 at the moment) but I say "Leave our Annie alone!".
I kinda guessed you owned an Anaconda due to your post. It's natural to have bias.
Although it doesn't stand true for everyone, the likelihood of those that don't think it's overpowered are owners of the Anaconda, or at the very least have someone in their group that favours one and it's semi-essential in some way.
On the outside perspective, it's absolutely overpowered, and it's crazy that it's gone on so long just to pander to players that would somehow be stranded in comparison, neglecting the other long-range Explorer Class ships. No they can't carry everything and the kitchen sink on a journey, but balance is compromise.
Which also holds true when new modules etc are introduced, Devs need to ensure it won't completely kill off certain ships which fit certain roles.
Balance will never happen if ships have to receive buffs to be in par with something so out of whack. Whether or not those ships need buffing should rely purely on something that's so far forward. The same stands for things constantly getting nerfed.
