First I looked in the "Stats" page, because that's where I thought they would be and they weren't. Then I went to Rankings and looked by team, I wanted to see the pickrate and winrate of agents by teams or tournaments and I didn't find it, but I decided to make the post to suggest.
After making the post, I decided to look at the recent tournaments in "Events" page and when I clicked on the last Faze tournament, I saw that there was an agent tab and there I found it.

Although I found it, it was still confusing to me what are those numbers, pickrate or winrate?
It has the defense and attack victory rate of the maps and what seems to be the number of times that map was played, but in the agents, there are several percentages per map and the first i think is the average, but it is a pickrate or winrate, I did not see be specified.

It would be interesting to see the rate of choice of agents in a specific tournament and even the rate of weapons purchased, we could see in more detail which weapon was purchased more often and whether any weapons are really outstanding.
We currently have interesting data on agents, but they are separated by player and not by agent itself.
It would be nice to be able to see how many wins Raze has and how many matches she has participated in a specific tournament or all tournaments so far.

It is possible?

Edit: I just found a page with these agent statistics and it was practically hidden.
But the suggestion of the weapons would be interesting!
