If they could just change something without messing something up I would completely agree.
That is highly unlikely. Multiple problems with this. The first, most of the material is simply Copy Paste. 2 errors come with this, the first would be like Defilers double hitting AoC. But the thing is, this scenario is actually really easy to fix. Which im confused why Helium hasn't fixed it yet. It would literally take 30 minutes. The second error is comes like Blood rage. here vtouch was copied from one class tree to another class entirely. This created errors which ended up with a super buggy skill that bypasses defense and does weird nonsense. This, I have no idea how to FIX, only to remove it completely.
But anyways, you can expect that no content will ever be released without a mass amount of bugs at the same time.
Oh and one other problem, seems their "test" servers are NOT the same as the actual server we play on. So some of the bugs he cant even replicate.
