PTR 5.0.15 Patch notes:

Storm has been fine for 15 years; do NOT touch storm. Protoss AoE has already been nerfed WAY too much; disrupters are a joke unit. Colossus are a JOKE unit that sees literally ZERO play in PvZ and almost zero play in PvP and they’re kinda bad in PvT; Protoss race does NOT function without AoE nor should it cuz this is not sc1.

So FIX colossus AoE so this so called “tier 3 unit” is actually worth the INSANE cost.
In their current state if they cost bout half what they do now it would still be too expensive.

Also lets talk harassments; Terrans have bout 6 different ways of killing their opponent before the 8min mark. As a protoss you have NO harassment VS terran until after the 10min mark and even then its costly cuz we dont get to evacuate our units with medivacs. Give toss the same tools to harass Terrans in the early game as they have for us.
