Please don't waste your early game advantages power/afk farming
If you have early game pressure, or are at least a strong early game lane bully, please don't waste your strong point playing passively. Champions such as (any by no means limited to) 
and
all have really good early games (yes, they tend to be good for most if not for all of the game but still, they have a notable advantage in the early game). So please make use of your strong point and try to get a lead, either in your lane or another's. Go for kills, poke a lot, look for that early level 2 engage/gank. It not only will get you ahead but it may also make your opponents tilt pretty hard, which is basically a win already.
although I don't think anybody in their right mind picks Garen and decides to passively farm their lane.
