effect of oracles maybe, like how many wards were killed with oracles up?

Don't know if it's possible, but you could do some sort of "enemies spotted by your wards" stat. That would differentiate good warding from useless warding.

While we are on the subject of wards could you make the timer easier to see and a bit more responsove? sometimes when I look at a ward that my camera hasn't seen for a bit the timer will be nearly full and then jump down to the appropriate time. It's also hard to see the numbers on tiny screens. Gold spent on wards would be a nice stat to track

If it's possible, limit it to counting wards placed outside the base.

Announcer saying "You Have slain a ward"

"Demonstones Denied to Xelnath by Warding"

Just have a wards placed statistic locally displayed after a game(don't make it a collective statistic of all your games, make it a post game statistic like damage dealt), if someone trolls and spams wards in fountain people will know themselves they are trolling, but if they legitimately place them you can't whine that the support "never warded" when they were actually getting taken out by an oracles, and you can point them to the graph where they then see you placed over 30 wards that match.

Seconds of vision granted by wards placed by player?
