Well i hope thats what you think, since its the point i've been trying to get across... aside from glyphs, which could be a gamechanger for many specs. Of course you can stop at 25, get glyphs and still have your gear scale 4 ilvs. Recently blizzard has been trying hard to "balance" low level pvp, and if they are increasing the bracket sizes to 10 levels, while reducing the pure quantity of spells all classes have, it is likely the amount of spells missed from lv 25-29 will be negligible for some classes (as it is now). Other classes may still lose some very core abilities, even though i think blizzard is trying to give core abilities and passives at a more consolidated rate in WOD.
