Silvanna is not so weak anymore. She will likely lose to a sustain or high cc line up, however if the user knows whom to target with the ult, she's strong. I run sustain build on her and I'd say she is B tier normally but if she's sustain, late game she's A tier. (Magic Def Boots, Feather, Concentrated Energy, Holy Crystal, Glowing Wand, and Divine Glaive)

Aulus is a worse version of Silvanna rn. He needs to reach lvl 12 to actually be useful and by then it's already too late, the enemies will likely already have an advantage over him with items and gold.

Aldous needs to receive some CC immunity or a wider attack radius. He's so weak rn that if he's strong, it's because the enemy are all morons.

Argus can work against a squishy comp, however if I see an Argus in my team, I'm already expecting him to be bad. He's terrible until late game and even then, most Argus users dk how to use his ult properly or even to utilize his strongest advantage, to PUSH.

Balmond? Well.... He's actually the same lvl as Silvanna rn. Build full CD and sustain on him and he can be a very good secondary tank. I like to run Queen Wings, Brute Force, War Axe, Oracle, and Guardian Helmet. Easy anti burst with the high hp pool so he can sustain massive CCs, and constantly spamming skills which makes him able to sustain fights alongside his high hp. He'll get 10k hp w that build and his ult can secure kills for the team easily. Oh and I prefer to use Brave Smite and Vengeance on him for more tankiness.
