Instead of changing Udyr's numbers, how about reworking him to not win or lose at champion select?
His design is straight up shit and doesn't work with how much mobility and CC have creeped.
The enemy team is either too immobile to escape him and he gets to run them down for free, or he can't connect with anything and is completely useless from start to finish. There is no in between.
Adding damage to Phoenix is going to do fuck all. The reason nobody uses Phoenix is because its damage requires you to stick on your target, which he can't do. Tiger's damage is similar, but only requires you to briefly connect with your target, not stay on top of them for 4+ seconds, making it functionally superior to Phoenix. Even if he can permanently stick to his target, there is no scenario where Tiger isn't sufficient to kill them, but Phoenix is.
This change reeks of incompetence.
