Lili serpent build is what you see a lot, it generates impressive numbers, however vs raynor the 4 target blind is handy ofc.
malf full dmg build I feel had he gone heal build might have contributed more meaningfully, since in that build he had 18 k hero dmg which is nothing.
nova build mostly fine, like you can argue for the aoe ult which is generally stronger then triple tap, but triple tap bring chaos into a fight, fucking up positioning and if it isnt blocked by buildings always does meaningful dmg.
butcher build seems a complete mess but he took some popular talent choices.
tass build also very messy, lvl 4 and 7 shield talents or lvl 7 static discharge, nowadays I prefer on him force wall as well.
muradin build vs butcher very very bad (no attack slow via lvl 1 and lvl 16).
tyrande ok mostly, super weird not to take lvl 1 cd reduce on trait.
raynor id say had a really bad build, nothing to help with the butcher.
naz build a bit weird.
jaina build fine.
and at higher ranks youll see much more synergizing between ults/ talents, generally the comp even with 2 premades in a team, but ofc the coordination is a bit dependent on luck.^^
had a game yesterday where first pick was cho gall and ofc he was heavily countered via picks by the enemy team, so I went morales
and we actually won^^ but ofc it wasnt just bc of my pick, its always a team thing, however those 110k healing were quite nice (tho common on morales if she doesnt get too much attention)
