I tottaly agree with your analysis that multiple times during the fights a few zealots might have done wonders. I think Harstem got a very strong opinion that in PvT zealots are useless in the main army, and in line with that, when fighting , he alwys uses them as harass. Altough I am a dia plebs, I will allow myself to disagree, i think he takes it to far. I do agree that if you got to much zealots and let them charge ahead they will die needlesly. But some zealots, hacking away when most of the terran army is dodging novas, is great. And without those zealots the protoss army is super fragile, specially against marauder hvy army. From what i have seen , thats also how MaxPax often fights in PvT, making terran dodge novas, and collapsing on rest with army that still has a fair amount of zealots
