Why not allowing mini wards, like 30 gold for a 30 second ward (one ward per person).
It's weird going from a SR mentality of warding saves lives to not being able to ward at all. By putting it on a trinket you could make it free but give it a short duration and a long CD. Wards would be used as a calculated tactic. You can ward a part of the jungle when you want to push up but then you can't ward the next time you push up 3 minutes later. Or intead of vision they are an invisible trap that only alert you if someone walks over them. It could encourage the sweeper item purchases, but maybe too much
By not having wards I feel like I can't be as aggressive, like once I push up I have to recall. Ever since the remake I haven't had an urge to play TT anymore. I had a lot of fun playing it with my two friends but the lack of tension over Dragon/Vile control and no wards just doesn't do it for me anymore. Nt saying it's bad, as I like how jungling is an option now, but the game feels a little too limited
