Add Clarity to Trundle's Ult

I have a short request for Riot to add to the pile; please add clarity to Trundle's ultimate.

I love Trundle. I think his balance is just fine, and he has a great niche. However, he has a bad case of hidden power. He's a rarely played champion, and at least down here in Silver, lots of players are only passingly familiar with him. If you asked someone what his ult does, they'd probably be able to tell you. But if you asked them to describe what his ult animation looks like, I bet you'd see a lot of blank faces.

For an ability that is so powerful, it's very easy to miss the visual cues, particularly if Trundle ults your team's tank while you're paying attention to something else. I've definitely had games where I played a tank, and backed off from a fight when Trundle ulted me, only to have my team engage the fight during his ult duration anyway. They didn't make a strategic error, they just weren't aware that his ult was active.

If you've been playing for years, you're probably familiar with Trundle and his ult, and this isn't a problem for you. But for newer players, even if they've played hundreds of games, they may only have seen a few Trundles. His ult animation should be immediately recognizable to everyone watching, even if you aren't watching him closely. For an idea of how to fix this, compare Trundle's ult to some other self-buff ults like Renekton or Nasus. The increased size and colorful, noticeable aura makes it impossible to miss when they are ulting.

For the sake of tanks and their teams, please add clarity to Trundle's ult.
