Giving heart to upgrade doesnt entitle you to it
Many people think that giving heart to the upgrade means they immediatly belongs to them. Giving heart to upgrade is merely a suggestion to other players that you are interested in it. Nothing more. If they cant decidie between upgrades which they want more or they are feeling generous they can but they dont have to give it to you. Yet I seen people melting over it and not onyl that but on my recent game two russian players in both russian in english started to insult host becasue of it till he kicked them from the game. That was the most justified kick I ever seen. Some people think that they deserve all the best upgrades and when soembody takes those upgrades instead he does that on purpose in order to piss them off. Its really sad thing to witness the diffrence between rogue core and deep rock player base.
