Basic Attacks against Rooted, Stunned, or Slowed Heroes deal 33% more damage. Each time Mei Stuns or Slows an enemy Hero she heals for 18 Health.
Ice Storm if you need waveclear
Reduce the cooldown of Cryo-Freeze by 15 seconds. Mei gains 50 Spell Armor while Cryo-Freeze is active and for 2 seconds after.
Cold Front is good too. Pretty sure Crystallize is just broken for survivability
When Icing ends, grant Mei and nearby allies 20% Movement Speed and 50 Physical Armor for 3 seconds.
All of these are decent, pick which one you think you need, skating away standard
After .5 seconds, roll a massive snowball that consumes enemy Heroes in its path. At the end of its path, the snowball crumbles, releasing the consumed Heroes, dealing 220 damage and stunning them for .5 per Hero consumed.
I think both of these are good, avalanche just doesn't feel like it needs setup from another hero
Basic Attacks Slow their target by 20% for 1.5 seconds. While Cryo-Freeze is active, Mei’s Basic Ability cooldowns recover 200% faster.
Icing’s Slow effect no longer decays over its duration. Icing deals 300% more damage to enemies very close to Mei.
Reduce the cooldown of Avalanche by 25 seconds. While traveling, Avalanche constantly launches a volley of untalented Snow Blind snowballs ahead of itself.
Flash Freeze if you really need it
