What about the reasoning behind the mount not being 110% speed? I can understand the weapon thing (even though I think its a poor choice) but the speeder not being top speed? Weird.
I read someone else post this and it changed my thinking: "It makes sense that it is only 90% when you factor in that it is down a motor and pouring smoke and sparks."
So people at 50 may wish to have the 110% on their travel speeder, but when you look at it as a novelty item and not a means of travel it all makes sense. It is not logical for the person who needs a Tier 3 speeder to get around. It does make sense to people that like odd speeders.
To me it wouldn't make sense for a broken down old jalopy moving at the same pace as a Porsche.
