Too many big characters.
One of the things I thought was awesome about Aganos is that he was unique in his size. He is HUGE! But with Arbiter, RAAM, Gargos and Eyedol, and somewhat Tusk, he’s just not unique anymore. If the two guest characters weren’t there and had two more regular sized original characters instead, then it wouldn’t be that big (lololol puns) of a problem, but Season 3 is just full of big characters! I just think it’s too many.
