Ok, so why didn't I try this before? It only seems like a recent 'thing' too. He clears well, sick ganks, scales well into late. That passive is stupid, too. I only ever have to leave the jungle to gank or refill my mana.
I go 21 into utility, rush mobility boots first item, with movement speed quints. If I get a good starting leash I don't even need an HP potion even with that.
I just run around ganking like a powerball rammus.
I max E too cause if you are going into the jungle just to farm your Q what are you even doing....
The faster clear speed for more ganks is more important than getting your what already will be too poorly farmed Q to be relevant slightly more farmed. Plus that armor reduction on E is really powerful when ganking lanes [normally top due to them being an AD lane]
