What's actually there are obviously 4 great romances for straight female gamer and 2 great romances for the rest. They still have a higher replay value with more different playthroughs ( as long as I'm not convinced with gender and sexuality switching).
But we haven't even played the game yet, we only know that because we follow the news about the game obsessively.
They have already said that you won't know if a companion is available to you until a fair bit few the game. The average gay or lesbian gamer will play Inquisition and come out talking about how much they loved Josephine or Sera's romance, and talk to their friends who may have romanced Solas or Cullen. Most people don't replay the game many times, and won't ever have known how many options someone else had, because the only way to know really is to look it up online.
The only people actually negatively affected by straight women getting a few more bonus options are the people here who deliberately look it up before the game is even released and make it a problem.
