Right now, it is well known that M Goliath is just inherently better that OG. But while I would like to believe they are both still good to use, the simple answer is one of them feels like its not.
Goliath is a brawler meant to get up in people’s faces and burst them down, unlike Meaty who is meant to deal sustained damage that overwhelms the Support and Medic. The issue is, that he isn’t able to burst people down, nor the range needed to sustain damage to keep up with Hunters. Now, good players know how to work around this, using Charge to single out Hunters, put them in kill boxes, etc. But there is one Hunter (currently in the free rotation) that just makes Goliath unplayable.
Sunny is just too able to completely shut down Monsters that don’t have a high focus on ranged abilities (which is all of them but OG). Her drones do not die in one hit like the Healing Bug from Slim, the Healing Bouys from EMET, or Bucket’s turrets, they have tremendous range (which Goliath does not) and they can be rebuilt as soon as they are destroyed.
So, as it stands right now, Goliath cannot and should not be used because he is just not able to effectively compete with Sunny at all. As soon as Sunny is picked, the game is no longer about fighting, its about Goliath desperately trying to chase Sunny down to destroy all of her drones, which isn’t possible because the moment one is destroyed there is another somewhere else, and you cant kill Sunny herself, because if you let the drone live it will shield her for too much for Goliath to handle, and if you go for the drones, Sunny is already back to full health when you turn around to target her again, plus, as I said, there is now already another drone.
Now, I love Goliath, I love the way he plays, I love his animations, the roar, all of it is great. But he just cant be played so long as Sunny is as powerful as she is.
If I had to come up with a way to balance it, I would say nerf the hell out of Sunny. Make the drone’s CD not start until its been destroyed, give it some kind of range I don’t care what so long as it cant shield from across the dome anymore, and make it die faster like every other drone in this game.
And I know what somebody is gonna say, “just use your flame breath to burn the drones.” And that works, sometimes, but if its more than 20 ft away from you the fire doesn’t reach it, using a rock throw spends half of your burst damage on a DRONE, and spending time to actively go over and break it allows Sunny to be all healed up again, placing a new one as the old one pops.
