please do something about this in next version
Rearm + Guardian Angel
another thing is Aghanims sharing with Greevil's Greed (Alchemist 3rd skill) and tiny ultimate (growth) can share for all of your teammate
note : it means when you want to buy last item to combine items if all of your teammate are near you , you can share your item with them and use it on yourself to get rid of Aghanims itself just at in some min after you combine it
thanks
