warden bonus TFT not visually obvious

I was playing around and decided on a full team of warden's to see what this bonus armor was all about. however as i furthered and furthered the bonus from copper to silver to gold , i saw no visual indication that anything had happened at all and was starting to get worried that i had a bug that prevented warden bonus from taking effect.

yes i made a ticket and they confirmed that the warden bonus is working for them , but they agreed that the lack of visual indicator's could make it difficult to discern whether you are actually receiving the bonus or not.

all i'm suggesting is a more obvious indicator that warden bonus is activated.
