Our succes might increase if our teammates stoped walking in front of plasma cannons that are being super charged and aimed at an enemy position,,,, ending with said devastator killing a huge chunk of the team,,,, Got realy anoied at my team mates that kept walking / stopping in front of my PC when it was 190% charged

Unfortunately, derptastic gameplay is a hard stat to track. On a match with my ork alt, there was a painboy teamkilling people rescuing fallen orks because they were stealing his xp... yet it wouldn't cross my mind to say all ork players are teamkilling xpdigging mouth breathing morons.
Cold hard math says LSM have a huge gap in win/lose compared to other factions, and orks are beating everyone, these are the only facts we have.

How about a simple reason/explanation: It's a buff to Power Armor.

Great, I always love specific numbers and prise the ones who get them if I can't.

Sooo what we can see here is CSM and Eldar are really close to baalnce(fluctuations like that above or velow 0.5 win ratio mean pretty much skill issues), LSM up, which we all know, Orks OP, which was surprise to everyone.

Personally I don't see this changing much in real terms, since there are factors more significant than armor rating at work. I.e. Melee system/Lag/Spammy combat

Across-the-board Power armor buffs are a cool idea and to be fair, it would be weird if they didn't affect CSM (tho I like the argument with Loyalists having blessed and well maintained armors compared to CSM outdated ones).

But I'm seriously afraid that it won't give CSM any more reason to play their tacticals than before, we'll just see equal numbers of traitor assaults and sorcerers with EVEN MORE pumped up survivability. My guess is that Chaos will get to no. 1 again really fast, especially when they fix Ork melee.

Because its a lobby shooter that needs to be balanced?
You want TT, go play TT.

Psst Older tech is better in 40K!So that argument doesnt hold that much!

Older tech per se is represented by relic armors, what I meant to say is loyalist techpriests take those same relic armors then bless and lubricate them with that sweet, sweet Machine spirit ointment which hereteks and dark mechanicum don't possess. But other than that, yeah power armor buffs should be for all users.
