Just read there is a lot of forums, I have actually at least 2 of them, the sky toss issue was discussed many times.
Sadly they changed the MS speed that was a mistake, so instead of fixing PvZ they messed up PvP and PvT.
Really nobody complained about the adept? about needing buff? needing redesign?
Read forums, I read at least couple of suggestions that they should attack air, and other different buffs.
That yes, many people (including me) wanting the adept being a more important unit during mid and late, but nobody asked for a glaive buff aimed to kill more workers, I think most protoss are tired of weird units and being forced to spam cheeses, most of them want to be able to play macro, use the biggest amount of units during a game and not being forced to just making the same compositions every game.
Also, there is a difference between whinning and debating/theorycrafting about posible redesigns, whinning is just whinning, it does not add nothing. Example, talking about tempest and how they would be improved, that’s constructive debate, whinning would be opening a thread every time a P tries to make them and lose for doing it and just writing that tempest are trash.
You dropped these 
Yes, Protoss don’t whine.
Just when they talk about emp 
Emp is borderline OP, so good it balances the lack of terran AOE vs Protoss AOE. At low level it is OP, stronger than the storm, you can farm zombietoss by spamming EMPS.
Look I have been hearing Protoss saying landed vikings kill their base with shield batteries and photo cannon. That is just my experience.
I believe all 3 race whine a lot.
If you believe your race whines less, I don’t care, believe what you want. There is no way to prove that statistically.
Yeah, but it is true that Protoss complain a lot about EMP, a bit too much?, and they not focus on their own protoss aoe, and the way they can deal with it.
Probably not a lot of complaints because not a lot of T at lower level make ghost, is a really underrated unit, the protosses that walk fearless around the map because they have a ton of HT would drop two ranks if T players started making ghosts every mid-lategame, and that would help t with practicing tabbing between stim-emp, some complains came from that side, and thats probably lack of practice.
“I’m not balancing whining, I’m just borderline balance whining.”
What?,maybe you misunderstood me since english is not my primary language and my expression maybe wasn’t clear.I don’t think is balance whinning because I think TvP is pretty balanced, what I meant with the previous message is that the power balance of AOE in pvt matchup depends on EMP,without it terran lacks AOE damage,tanks are good but they are not good enough against archons.Many terran struggle because they can’t beat protoss with single target dps.
And the OP comment is vecause at lower level Protoss player do not split their HT,they just walk around the map with clumped HT,they base their gameplay on storming the terran so EMP is a gamechanger at that level,you can go from having to fight against 14 storms to just 1-2.
Does overpowered mean something else in your language?
No, but borderline could be interpreted on the wrong way.
It still strikes me as closet balance whine.
It is not because if you continue reading you will see that I think it is balanced, it is classic assimetrical balance strong things in one side, other strong things at the other side.
That’s why it’s closet balance whine.
These are complexes mate. The will keep whining and they will keep repeating how hard their race is. It’s pure psychology.
