Just got through reading this post and I will say two things: First, congratulations on clearing 143. That is truly amazing. The second is how I am deeply disappointed in Square for, not only this response, but this "end result". Not only is it a slap in the face, but it is a sure form of lack of resepect for their gamers. It's not enough that the GM had no idea that Incursion can go beyond lvl 140. But the players themselves actually had no idea level 143 was the cap. SE never released this information. And if it was released, the problem is why there is no reward or finale for completing this content? It's almost as if SE decided "nobody is going to clear this content ever, so we'll just stop riiiiight here..."
That's really poor game design for the elite players. I'll admit, my GEO isn't anywhere close to being in this content, but for the players at the top of the tier chart, they have really disrespected the time and effort that was put into clearing the challenge. And the response? "Velks are mean, and they take away your KI". What a silly way to end a content clear. The funny part is, Where in the game dialgue does this explanation ever come up? It's one thing to say that's the expected outcome, but you developers didn't even include that verbiage in the actual game.
Sounds like a classic "Oh, crap....We got nothing for that" response. Admit the flaw.
