I find it pretty ridiculous that Oggok together with Zeffi control vortex by making your entire team immortal, allowing you to fight for 20 minutes every time. Completely trivializes the encounter and forces players to have them in the team.
Those 2 heroes together throw competition out of the window, strategy? Not required, just throw 2 heroes who alone make the entire team immortal with a 100% uptime.
The suggestion? Something has to change with how vortex handles this. I don't have a decisive answer to this fix, but at the moment what those 2 heroes are doing to vortex can be considered a game breaking issue.
Why? This is a game based around seasonal ranking races and it is a strategy rpg. Those 2 heroes are breaking any form of strategy and are required in order to compete.
If you have them? Easy, only other people with them can compete with you.
If you don't have them, then it is impossible to compete against people that do.
Both ways breaks the competition.
Perhaps make it so that Poseidon ignores immortality. There is only one thing the immortality buff is used for and that is to cheat death and continue living. This mechanic breaks a game when you can have it active 100% of the time which is why rpg games never do this.
