I dont believe gorgons was every solid in place- just ideas.
But Krakens was going to be Eye of the storm. It would give him damage reduction based on his range from the hunters. a HUGE “meta” problem for kraken was the amount of post-dome chip damage he would take between domes (more specifically, just after one). This is a HUGE reason the “supposed to be squishy hard hitting mage” monster had such a large health pool, he needed it against teams who knew how to deal damage- and knew how to deal it as he was trying to escape (he was quick across a map overall, but lacked notable burst mobility and his traversal mechanic meant he was constantly in LoS).
Keep in mind kraken was getting a very large overhaul, with many of his abilities being re-worked (aftershock being a big one).
Meteor goliath was going to be given persistent aoe flames from his abilities.
