FYI if your jungler is expecting an invade its YOUR JOB to help them thats YOUR teammate
Dont farm under your tower for a measly 5 cs! if your jungler dies you lose map PRESSURE, golds dont understand this so if your gold and reading this and u have trouble winning due to "faulty" or "trash" jungle its cus you dont help them and the slightest lead can keep your jungle handicapped permanently due to how hard it is to catch up on exp/gold with the opposing jungler taking all the camps. I see this mistake all the time even if it happened ONCE that's all it takes to make your jungle go 0 9 rather than carrying, its really hit or miss assuming you KNOW how to jungle good.
