Any Demigod can swing the match around imo. Its about portal capping with flag lock late game

Rook can easily swing a Fortress mode map due to the ability to go up and tank the Fortress while pummeling it into the ground.

Regulus is good at swinging most maps.

A well played QoT can swing maps pretty well too, but so can any Demigod that is well played.

how late game are you talking? and if you are gettign pushed on being able to cap a portal is very rare. I doubt most people wil b able to break through defenses and grab it, and even so, you ahve to have giants practically to make it worth something

Depends on the Map as well.  In Exile, Erubus can bat swarm across voids to any flag he desires while the enemy is up front battling it out.  This creates a distractions causing them to withdraw a bit of force just to recap flags.  I promise you, in order to catch up to Erubus flag capturing with bat swarm, they are going to need 2 demigos recapting the flags.

Regulus, any map, any time.

I think a late game rook can be hard to beat back everyone know what i mean .

Rook can be dealt with easily at first but then when he levels up a fair bit and his health is over 7000 hes hard to beat back it really needs a tagteam to take him out

If the game is in the end phase and you're on the wrong side of it, there's little Regs can do.  Mines doing 2k damage means nothing when even QoT is packing 5k+ hps from arties.  Rook really can make a huge difference, as can Oaky.  On the other hand, UB/Erebus combo rush, aka (Evade! Evade! Evade! Evade! Evade!) I've seen pull a bad game back from the brink especially in maps like Exile where both sides get Arty shops.

late game is hard for a most. i really meant those o-shit-we-are-on-crucible-and-they-have-been-taking-out-towers,-almost-in-base

Yeah, if you're pinned back in your base, you're pretty much done for unless your opponents make a huge mistake and all get nailed at the same time.

Erebus can build a pretty good army late game, and very quickly with a bat swarm. I've turned a game or two around that way.

I think Rook is a good one for turning it around.  Focus on taking out their buildings and capping their portals.  This is especially effective on maps like Cataract.

Imho, it would be oak. His infinite supply of spirits keep him dealing out good damage, the enemy distracted, while he heals with divine justice. The more croweded the combat, the better he gets. When the enemy is at the gate, Oak stands firm and sends them packing.

I just played a really long game with my brother, I was Oak with Rook, and he was TB with the vampire guy.  I fought all the way to his citidel, but once everyone was fully pimped out, the vampire guy became invincible, it was not possible to kill him, Rook and I pounded and pounded, but he killed our citidel nearly singlehandedly while enduring the pounding. 

Support QoT with shield is pretty good at it...especially when paired with Erebus/UB, makes them almost unkillable.
