There are 5 reasons why AP Godyr is good. The 1st one is that you can clear camps faster. Clearing camps as AD Udyr doesn't take that long but if you build AP it doubles the clear speed because of your phoenix. Its basically a permanent Rangers smite, just less damage. The 2nd reason is that your better in team fights. Your ult on activation gives you an AOE damage source, so instead of focusing one person you can focus the entire team while still attacking the person your focusing. The 3rd reason is because your a better duelist. As APdyr you can burst down people within seconds because most people will build armor to block the ADC's damage, and they think your AD. The 4th reason is that your a better asset to your team. Most Udyrs believe their Trick2G and that they deserve all the kills. As AP udyr you allow your teammates to get kills so they will like you more. The 5th reason is that its fun to play. League is about having fun. So what if you do bad, your still having fun playing with your friends. Don't let people tell you what you should do. If youw ant to play AP Reksai or AD veigar then go for it.
