Maybe it is different here on EVO, but weapons have, in the past, affected a players ability to meditate. Osi rules that is-- and i was told that EVO shar runs like OSI--- so... that brought me to my conclusion: that natural meditation would be effected by non med-able armor and weapons. Also, most people like using scripts for raising skills, which would include the use of the meditation skill.
That all being said, magery is rather easy to skill up here like everyone else said.
