What if they couldn't get the copyright?
All the models would have to be changed, and even the names and titles of some heroes would have to be modified. The names of the equipment in the game would also have to be redone.
Although for big players like GA, this kind of change was not too troublesome, it was too damaging to the original group of players of COG. Many people liked COG because they liked the hero characters in Azeroth. If all of them were changed, the whole spiritual essence would be different.
However, there were also speculations that Clive Lehmann and GA wanted to make the game a game that would be popular all over the world, and wouldn't be restricted to the original player base. So to them, even if they couldn't get the copyright, it would only be a small setback, it wouldn't be a big blow.
Some people were confused.
Some people felt pity.
