Just been screwing around a bit in ranked lately
No I'm not talking not trying. But I'm talking randomly walking over to the enemy jungler's starting camp to make them paranoid and throw down an early ward or 2 and walking back to lane not caring. Other things include running around in the enemy jungle (as someone with decent mobility such as Riven, Lee, or Udyr) over wards causing 3-4 people to chase me around while my team is pinging me danger and I'm just kiting them around the jungle and my team is taking towers because apparently someone mindlessly walking around in the jungle is worth chasing for 20+s to kill (yes I use a ward trinket upgraded to juke them). Sure I'm wasting time, but if I waste the time of more than 2 people I think it's pretty well worth it.
It's also funny to let people who think that they normally lose lane think you are bad by letting them push you to tower and then all of the sudden flipping the switch and dominating them with people like Darius (last game I did it to a Wu with Riven).
Sadly enemy teams fall for stupid stuff like this all the time and I do get the slight edge over them and its funny for them to not realize it. The funny stuff you can do in lower elos.
