So I mostly play Joust and select fill with casual games. I mix it up when its time to play a guardian, but Ares is fun to play so I pick him from time to time.
When you end up with 2 or more of the opposite team NOT getting Beads, its almost like cheating. Im not sure Ive ever lost a Joust game with Ares when the other team didnt counter your ult with Beads. But on the other hand the last two games I have selected him all 3 members of the opposite team selected Beads. At that point I almost feel useless aside from as a soak. It makes the game way harder especially since I play on console so his (X) chain spell is considerably harder to land than it is when I used to play on PC with a mouse.
So what do you do if the other team counters your ult? My strategy had been to load up with items that reduce CD. Try to burn the ult once and hope your in a situation where you can use it again before the beads cooldown. Doesnt work too well until late game.
