DIANA COST WAY TOO MUCH MANA NOW

was playing a few games and noticed how quickly i run out of mana with Diana now after a combo. one full combo of all her abilities left me with barely enough mana for q and w. i do not think her w should cost one hundred mana, i think her ult should only cost 50 mana, and her w should now cost 100 freaking mana it is not strong enough, i think 70 is the most it should ever cost. i dont think riot took into account that only one her recommended items give mana, and thats lich bane, it only gives 250 mana. pls riot at least take this into consideration if you see this
