She is getting changed, but based on her kit, she was designed as a PVP Toon anyway.  I certainly don't think anyone except for Bronko's early viewers would've decided to go for this fusion because she was gonna be a PVE Monster. That doesn't seem obvious. 

What is obvious is the constant failure to adequately test. 

It is the principle of the thing.  They are gamblers.  A casino will check all their equipment to make sure it is working properly.  This gang is too lazy or too cheap.  

I dont like being cheated.  If they will cheat you for $2 they will cheat you for $2,000.  

I don't disagree, and have actually made the same "it's the priciple of the thing" comment multiple times about Plarium behavior.

In fact, I stopped spending entirely over two years ago because of the repetitive "principles of the thing".  I vowed to never spend again until Plarium changed their shady practices.....Here I am still playing the game, and still not spending. I guess I didn't care enough to quit. 

As far as the complete lack of testing? At this point, I expect nothing else.  Plarium has set the bar that low.

They nerfed her before the event even began. The announcement was made on Friday morning.

Yes. Hours after the Summon Rush Began, and a day and a half after the Fusion started.

pretty sure they do it on purpose to get people to buy in then kill it afterwards

Alright, that's fair. When I woke up, I'd already seen the announcement, but timezones and all, so, I'll give you that.

It might be their actual intent, but it sure looks that way.  That is why they should offer every player doing this fusion a big compensation.  

And they need to test all new champs before rolling them out.  They are hurting their own credibility.  A gambling house that gets a reputation for not being legit wont last long.
