The balance team needs to start making some sort of effort to wash away this tide of unbalanced protoss that is festering the ladder. Let me propose a solution to you:
There are two even players of slightly above average skill. One is playing Terran, while the other players Protoss. They both perform at around 150 APM, and have equivalent game knowledge.
As a Terran player, what can you expect from a protoss? You better scout for any proxy, whether it is cannon rush, proxy robo, double gateway, proxy stargate, or just a battery hold on your third base. Ontop of this, you must also scout and see what they are going. Blink stalker pressure, DTs, chargelot warp-in on your main, colossus, skytoss, phoenix opener. If you fail to scout properly from either the proxy or the seemingly infinite possibilities of harass from the Protoss, you will lose or be behind greatly.
Now, lets look at the Protoss:
Check for a proxy barracks, and factory(starport will be late so youll figure out before it even builds). Mine drop, regular drop, hellion drop/runby, banshee harass. Now, the protoss has to scout for what the terran is doing, lets look at the terran’s options : MMM, mech(lol have fun with zealot immo), and skyterran(which is completely shut down by mass stalker anyways).
The Terran has to prepare for SO much more, and has way more potential things to swat away compared to the protoss. Ontop of that, the micro of a terran army is clearly more demanding than protoss(a move race). The most they micro is blink, storms, and disruptors. Terran has to EMP, split disruptor shots/ colossus, and avoiding storms( 3 forms of aoe btw!) with some of the most fragile units in the game. If you want to go mech, you can say hello to mass immortals that will proc their absorption barrier(100 dmg), and chargelots that will just run into your tank line after absorbing 3/4 tank hits.
Its time that we put a stop to this, if youre going to have units that are EASIER to manage, why make them more POWERFUL? Its like Terran has to play 4D Chess, but Protoss has been playing checkers all these years, and still dominating zerg and terran.
