I think, if they are bothering to go to this point. They might as well make a piece of loom for every slot. They have stated prior that they don't want to do this because they believe at least a few upgrades should still feel worth going after. Most people that are going to use looms in the first place are doing so just to get to the end as fast as possible. They could careless about getting upgrades along the way to cap. This is the reason I won't bother to put all my looms above the 90 cap. Its not like it really takes that much of an effort to get to 100 once you been through the content once or twice and learned the fastest path through to the end. The only reason all my looms are 90, is because they were grandfathered in, otherwise they would never saw 90 either.
