A new addition to the mid-lane is D'Arcy, well rounded and with great potential for both duels and team play, allowing for some of the most creative plays in AoV.
For a while, I have considered Sephera to be a relatively weak champion but recently started to notice a pattern. She is annoying to play-against and extremely difficult to kill. She is always there, near the fight, removing opponents health little by little, and there are almost no clear counters to her.
Another addition to the Mid-lane legendary status is Elsu, extremely long range/high damage marksman. In addition, his unique capabilities of placing vision wards dramatically increase the safety by alerting about incoming ganks.
In Gold and Plat leagues, one of the most important things to consider is ally team composition. For example, if allies are lacking control, Aleister’s value increases. On the other hand, if your team is filled with control-oriented champions someone like Natalya can really shine through.
In Diamond league, this gets even more complicated as the enemy composition needs to be taken into account.
