First!

That this passive (and especially ignoring unit collision) can make for some insane poking, especially when finishing with a Q through E or a Hammer frenzy. The thing is that whenever you want to combo from Hammer to Bow for the poke, you'll mostly want to transfer back to Hammer to finish your combo. Most of the time your poke will transfer into a fight/leave you exposed: this just takes too long to be really effective..

Starting your poke by transforming from Bow to Hammer, running through the minion wave, will allow you to start a combo with Q much more easily. Don't just poke, commit a little longer for the combo and you will be able to change back to Bow when they back off to finish the job of - you guessed it - doing tons of damage.
