Thanks for all the feedbacks everyone! Glad to see there's a good chat about this topic!
Yes, most of you got it right and an actual (complete) Victorious set would be cool as well, given we already have the blunderbuss that's actually a pretty good idea vs a golden sea dog set (which could be the same, actually)
There's also the Courage Set which fits well but that's already been given out in some parts so I don't think that's applicable.
And indeed, players who reached lv50 already had the Good Boy ship set, but that doesn't mirror the actual dedication for all the commendations.
I've got friends who has 50 but don't have even half of the commendations, maybe because some levels where purchased with dubloons, maybe because they mostly stayed on the ship and didn't do much killing with the weapons, and so on.
Just like Year 1 Legends had to the Animal runs, without knowing that in the future there would have been faster, easier and funnier options.
While I would be sad for them, an extra reward would really mean a lot for the people that indeed, were able trough effort and patience (freaking matchmaking.) to get the 100% of Arena (❤️).
