When I say higher ranks I mean past 16~15. Its already a trouble to keep minions on the board. Isn't he better replaced by a plain taunt minion like Shieldmasta or maybe the cheaper 2 drop Sunfury Protector?

Shieldmaster is rubbish. Some players have been switching to sunfury for earlier taunts/more mana for combos.

You can't handle the truth.

Nothing wrong with dat Shieldmasta.

But on topic: Yeah, depends on your deck Sam. With the 2/3 nerfing, whilst only a slight nerf in the scheme of things, it does mean that Argus should find situations where it can buff the two minions; If your deck cannot find this situation more often than not, then he is not as good value as other options. 

For instance, I run him in a shaman deck where I can always put forward a totem in a pinch, whereas I don't run him in a druid deck as I have better options at 4-cost for my needs. I put pictures of both decks Here somewhere. But yeah, if you think he isn't reliable enough for you, then I reckon go with your gut and replace him.
