the fact that he opted out for MKB and not Battlefury to replace his aghs slot was a bit questionable in my part on his decision making. he could have made his life more easier that way. therefore I conclude this guy lacks of training..
In most of the fights, Doom really should have been using Doom on Puck instead of the others as it's the one dealing the most damage with its spells that keeps killing the team, has the most net worth and gives value over using Doom over heroes like Axe and Ursa.
HOT TAKE: The only reason you did so well is because you had a Sand King on your team. I currently have like a 95%win rate with SK. He's broken at the moment.
