"Time is running out. The Nexus is not ready. All my life, I have stood against the forces of darkness. I wield my power to protect the innocent. While I was not born to this realm, my duty remains. Now, I sense an approaching evil that is all too familiar. I am the Guardian Medivh, and I will fight alongside these heroes! We will face this enemy together... and together, we will defeat him!"
Under the influence of the demon lord Sargeras, Medivh opened the Dark Portal and unleashed the orcish Horde upon Azeroth. To atone for this sin, he rallied a new generation of heroes to stand against the Burning Legion during the Third War. In the Nexus, Medivh continues to lead his allies to greatness. He observes the battle from up high in Raven Form, then swoops down and uses shields and portals to turn the tide of battle. Now, he takes his place amongst the legends.
No longer will Warriors have difficulty engaging with the enemy team’s back-line thanks to Dark Portal. The terrifying damage and lockdown of Arthas combined with Medivh’s Dark Portals can instantly ruin a safe Assassin’s day.
The scouting and positional information gained from Medivh’s Raven Form helps Chromie stay one step ahead of her enemies, landing skillshots with ease even while enemies hide behind walls and structures.
Lt. Morales’ healing potential is practically unmatched, but as most players have quickly learned, she is pretty easy to kill if caught out. Force of Will is great at mitigating incoming burst damage, and even the most dive-happy team will have to think twice about the resources they commit to killing Lt. Morales with Medivh by her side.
Any hero that brings consistent, sustained damage will often put on more pressure than Medivh can handle. With Valla’s constant barrage of abilities and auto-attacks, Medivh will struggle to keep his team – and himself - alive.
Large area of effect damage abilities can be a major nuisance for Medivh to deal with. With the option of using Force of Will on multiple allies coming online so late (level 16), a few well-placed Blizzards in the heat of battle will have him scrambling to figure out who to save.
The perfect Dark Portal engage can be completely nullified if your team is unable to follow up immediately. The silence and crowd control effects of Sylvanas’ Heroic abilities are very dangerous against teams looking to make good use of portals.
