Donkey is the courier. Someone on your team should buy one in every game. Usually this is a 'support' type hero's job. It can be upgraded to fly to more efficiently transport you items. Item recipes are necessary components for higher items. You buy the ingredient items + the recipe to get the better item. Yup, right click is buy. I rebind to my side mouse buttons. I don't tend to need more than 2 active items. Not sure what I'll rebind to if I need more. Haven't checked if the Shift+key binds work like they do in HON. Groups are important because some heroes will have you controlling multiple units. eg, chen, meepo of they add him. Eating trees great and cheap way to heal. You can use it strategically by eating paths to escape, eating a tree to get out of furion's ring of trees spell. No there's no bushes. Camera seems much the same as HON and War3 so not sure of the problem there, but I've not played LOL to compare notes. I'm also having trouble with my last hits. I'm too used to the little last hit marker in HON, made it pretty easy.
