We had those reqs for repair like 180% for 3rd lvl profession level and what? People did alts for 3 sg profs, 3 bg profs, 3 armor profs, and that changed nothing, also making another repair alt to repair stuff... leave it as it is now, its best system, now you don't have to make 10 alts for crafting three several things, and its good.
If someone wants to repair stuff he'll make another alt, what's problem in it? My main lumberjack does it good with 170% repair, no need of tools or uber skills, 100% is also enough to repair basic stuff.
