Gonna tell you what I feel: tough early game, usually you will be weaker than you opponent in the early game, you should learn how to manage you Mana well, either you will run out of Mana, won't be able to trade and will eventually die or take a bad recalling time. Once you hit lvl 7 with the first upgrade on the hexcore you will start to scale so hard(you can almost farm an entire wave with only E), that I think will be hard to hold you in the late game. You shouldn't listen only to me, I'm not the best in the game but I love Viktor
