Is RMU missing an opportunity to fix the rules system?

I have been doing a bit of homebrew rules writing this week and I have taken bits and bobs of other games and mashed them all together to get a set of rules that did a particular job. It isn’t rolemaster so doesn’t belong here but bits of rolemaster ended up in what I was doing.

Now if you take bits of different games you get different mechanics and different ways of doing the same thing. In rolemaster particularly RM2 if you look at how skills work you you get different ways of doing things in the same game!
