thoughts on Aurelion Sol

After played some games with Aurelion Sol, some are great, some are not, I find that his CD on his Ulti early game is kind of too long (2 mins at rank 1). to me, his ulti not only a damage dealer, but also a great life saver for gap closing champion, since we cannot reactive Q right after its fired. more and more often, enemy just keep dive in on me in the 2 mins CD time. maybe there is something I did wrong, but that's my thought. if someone has a solution, pleas do share.
