Guys, please stop picking Tyrande as a 'supplementary support' to Tassadar

The heroes want to do EXACT opposite things and the entire game you'll be struggling with a disjointed draft.

Tassadar wants to enable a squishee auto attacker, he wants to sit back, clear waves, win the macro game. He is defensive, good in longer fights. His burst damage is worthless.

Tyrande is all about burst. Yes, she has a heal, but it's negligible in the current metagame, where half the warriors have a higher healing output than she does. She's basically another ranged assassin. She wins the fight in the first 4 seconds, or the fight is lost.

Sustain vs Burst. Enabling vs Blow-up.

Two semi-supports don't make a whole.
