Let's analyse the game a little bit better.
Firstly i'd like to thank my teamate Anticaps who reported a situation and the fast reaction from the stuff.
This is the active community we need which will certainly improve the experience for all of us in the longterm.
For the game in question let's look some facts (not comments, opinions, experiences but cold hard facts):
All towers were up until min 40.
The enemy wouldn't pass the river w/o tower loss.
Was 2nd most ‘’Dmg done'' to enemies and 1st ‘’Dmg done'' in towers.
Even the enemy commented how effective i was (chat is available in the replay).
The Treants were indeed giving gold to enemies BUT how much specifically will be based on the basic financial principle called ‘’opportunity cost''.
You spent time to kill those treant which give 6gold each , time which could be spent farming woods or other lanes or attacking the enemy team.
All over activities would provide you much more gold than treants.
The best participation a Furion could have in teamfights in this setup would be his ulty (with agha) which was there in every situation.
I was using my items when the situation got unbearable in a defensive manner.
As stated in the beginning, i appreciate the administrative reaction BUT,
if you want to ban me for something, make sure it's a valid reason.
