If yall want wards, you guys probably dont need help with that. If you wanted some alternative to the standard vision thing, I was thinking maybe tripwires or motion sensors? Could even have different prices for single use, visible or hidden ones. There is certain utility in say, putting a tripwire down in enemy basement, and they dont know when they set it off, so you go and kill them. But also, a sensor they DO know about, and then they have to make the choice if they want to stay, lay an ambush, run away etc. Could have some really interesting bluffing and strats. I can imagine putting a tripwire somewhere their carry wants to go, and then they set it off, and then you guys dont show, and their team may feel forced to vacate the area or commit multiple heroes to defending it, and it ends up wasting their time. Just an idea I had
