I'm not going to through the thread again for quotes, but I agree with the people saying that there is an ethical problem in this.
When it is acknowledged that the summoner makes the game easier, he should be a part of the core game. This is especially the case if he is meant to fix the very difficult transition from insane to nightmare.
I realize that Trendy needs to make money, but in my view an add-on should give people other viable options when playing, but not actually make the game a lot easier. Even more so if this change is more or less mandatory for people without great skill.
BTW I'm not surprised that a majority likes that the game is made easier (I'm not saying whether it should be, just that I think the result of the poll was predictable from this perspective alone).
Despite the above I'd like to say thanks for a great game. I don't think I've logged more than 300 hours in a game since Civ 3!
