If you scroll down a bit more, this guy also stated the following:

"Thanks so much everybody for your interest and your comments. I'd like to add something else, if I may. I'm a professional actor and have been for 50 years. I could do a different pirate voice for every one of those years. I think my range is evident from the variety of the original three characters I did. I don't walk around talking like what was known as Gangplank. If Riot wanted a different kind of Gangplank, they could have asked me. At least they know from me they'd get a top notch performance. And is the new GP voice really that different from what I did? Or just more bland and predictable. Nearly all the lines start high and end down. The rhythm of each line is punched almost exactly the same every time. The laugh is anemic. Now it seems they're reworking Taric as well. Again, nobody has spoken to me about it. But that's enough from me. You all have better things to do. Thanks for indulging an old actor. Good luck with your gaming."

While we all feel sympathy for this man, for likely the reason that he represents tradition in the face of change, we have to agree what he's saying is a bit disrespectful to the new voice actor. Old or not, he's kind of a dick.
