Okay I like it, but other comments mention the passive reveling stealth champs. All that could be done is remove the ability to reveal stealths. Also the mines could revel enemy champs for 4 seconds(such as nids traps, caitlyn's, teemo's. This would make it affective to play them like wards. W also seems really weak you didn't say how long the active was, the damage isn't great allowing for him to be bullied. W doesn't have a good time limit. Mines auto explode in 1 minute, that's awful. Allow them to stay say for 5 minutes then have an active ability to detonate them/when enemy's walk on them they explode. Because as of right now they're just ranged weapons that are really weak. You should look over your abilities and see what they need. I love the idea man it just needs work imo. We could finally counter those pesky stealths ^.^
