So there ya go. Unintended. And that is my argument. It’s the same as using an exploit. Until it is nerfed into not being as strong as it currently is. Until I clearly knew what a terminator build was, I was of the exact same opinion as yourself. That it’s just using a combination of skills built into the game, and making effective use of them.
Have a read of the thread I linked as it goes into it all in extensive detail.
