Hey everyone recently i've specced arms and i noticed the bladestorm wasn't doing a lot of damage as it used to. I'm not sure if it got nerfed or not but still i think one of the fury glyphs;glyph of slam, is much better than bladestorm considering the glyph gives 5% extra crit to it in which is the arms rage burner, opposed to 15 seconds less of a cooldown on an ability that won't do as much damage as it used to. Anyone agree?
