They should make new wards for this map, that give line of sight to a similar size of teemos mushrooms. Have the wards cost less then 75 of course but it forces them to be strategically used, and you have a very limited time to see someone pass by them.

The lack of wards is a good thing. a few words could give vision of the whole map on TT. Wards would be a choking presence here. A few wards could give vision of the whole jungle and prevent the enemy team from doing anything. As soon as they step out of the base you know where they are and can shut them down.
There are only 3 champions to keep track of. Gank prevention isn't really needed. You're team can see the missing players and move into a position to counter aggression. How it is now is fast paced and fun.

Personally i'm not a fan of map hacks, and have no idea why you all seem to like it.
