You can acutually play with peasent gear when you loom it. You earn a little bit more money, and it is just as playing with vanilla items. Fuma is an example we know all, but lots of other players think the same way:
Adal uses a Nordic Short Sword +3 instead of a Nordic Short War Sword, Mala uses a Short Arming Sword +3 instead of a Broad Short Sword, I use a Nomad Sabre +3 instead of a Liuyedao...
Who would bother looming these items at the opportunity cost of leveling with 50% speed? I want to see rare looms in the battlefield in the future, too.
Besides, what do you think when you introduce an eternal double exp system for players who don't use looms or are gen1 will happen? The Hetmans and kinngrimms and Egos among us who are level 35+ will not level to 36, but to 37 just because they can. The difference between their level and the one of a noob who just started playing will be even greater. It would even be realistic to plan a level 36, 37 or 38 build to reach one day, and as soon as these people are done, they get their looms out their closets and dominate all the servers.
Gotta respect the rules, man.
Logic reasoning works only when there is no argument about the observed facts. If you want to prove that C causes A, therefore no B, gather data and run a regression analysis. Then you can come back with your inferences. Otherwise, how about we just respect that one can see this differently and we stop arguing about it?
Refering to your avatar: A real sir does not downvote every post of people they don't agree with. It's not a nice way of discussing. Different opinions help finding results and thus, help the developers. You can downvote kinngrimm when he designs a TC about himself in the EU TCG thread to tell him he's not the centre of the universe, or a Kapikulu who gets all mad and makes a thread about it when someone jokes about the correlation between teamkills and his clan, or Nightmare798's posts out of tradition...
