Maybe I’m just seeing this wrong but okay let’s drop forur from the list of 13. By my simple math that still is a 9 to 1 or 9 to 2 advantage even if you count Eclipse/Eos as a Raid.
Now let’s compare arenas/Cirles of Slaughter
TPS = One excellent, one good, and a halfway one if you count the Dahl combat area
BL2 = three very good, one excellent and a half if you count the bar brawl. Not to mention a superbly difficult didgistruct peak.
So by my simple logic 5 1/2 versus 2 1/2.
Part of the reason for this is a lot more content was released with BL 2 but even if you stripped out much of the extra content the endgame value was still there.
And I know this has been harped on till people are blue in the face. But the real value of borderlands 2, the reason folks stuck with the game so long was because of all of the different things you could keep doing AFTER finishing the story line. Competing, farming, theory crafting, trading, rebuilding, experimenting, etc. that one could do once you finished the main storyline. And whether folks will agree with it or not in my opinion that was the real difference between the two titles. And what kept the Fanbase interested and the excitement level high.
