Vantaggi
Mythic was acquired by EA due to the huge commercial success of DAoC. Since then Mythic has done amazing things. Warhammer was a AAA mmo and without Mythic SWTOR could still be in production. While EA had all of its eggs in the SWTOR basket no investment was being made in future projects at Mythic. U4E became messy, a game originally intended for mobile and meddled with by both Bioware and the mobile group. Great things were being done at Mythic when we moved forward and launched Dungeon Keeper. Mythic had great leadership, creative minds, and very technically proficient people. It is a travesty that it does not exist anymore.
Svantaggi
Lack of support from corporate. Warhammer Wrath of Heroes could have been a MOBA of the same caliber as League of Legends. Corporate would not market it and thus it did not get out of beta. This is just one example out of many of how there was no corporate support.
