i agree entirely that the glyph system needs to be totally revamped. on each class there are several glyphs that are either totally useless, or cost way too many points for how useful they are.
there is no point in having glyphs in your game that noone ever uses, they are just a waste of space on the server.
i suggest removing the "useless glyphs" and replacing them with "interesting glyphs"- things that ppl would enjoy using just for fun.
these interesting glyphs would cost 0 or 1 glyph points and maybe change the color of an ability, or do something else interesting. in every day scenarios they would be generally useless, but people would still use them to get that "last point" in their builds that they cant fill out with any other ability.
another thing i suggest is having a couple of large costing glyphs that give you a special ability (balanced ofcourse), if each class had 2 or 3 of these, then there would be some variety between players of the same class, as opposed to everyone having a cookie cutter build with all the useful glyphs and none of the useless ones.
