Percentages

It's just that someone clearly isn't taking into account the players, most of whom clearly don't have good gameplay skills. In these games, it's generally difficult to "execute" anyone, as they constantly retreat to neutral zones, and when they're also immune to execution, the point is lost.
And no one ever takes a particular side when they start reasoning from their own perspective, just to make themselves feel good and comfortable, possibly even without having any experience as a GM. The point is not simply to create cool roles, give them a bunch of non-damaging spells, and abilities, in order to quickly attract players, half of whom will still be slow and unresponsive, and the other half will sit and wait for the game to end, because nothing can be done with such a set of skills and players.
