Your second combo also uses EX-Flame aura which in my opinion doesn't make a lot of sense sacrificing 1 meter for 3% damage and tighter execution link for s4, but first combo is cool, how tight b1-spear link after ex-tele? Is it consistant or you have to be very precise in run timing? Cant check them in game yet, but if spear link is not consistant you're pretty much getting yourself full combo punished for doing this combo occasionally.
