Okay, since you try to talk retri down all the time and compare it to Arms, ill give you some facts:
You can handle Affixes, you can CR. These 2 single or lets say 3 abilities with HOJ alone are stronger then the whole Warro Toolkit BY FAR. I wont mention freedom, lay on hands and other stuff, which a Warr can only dream of having.
So for a group, a ret is far more helpful, then any Warro could be.
Damage Raid:
After the buffs, Arms parses 282,072.38 DPS on average, which now makes him 5th last.
Retri parses 300,010.06 which made him middle of the pack. Before the buffs it was Arms beeing 2nd last with 269,850.76 K DPS and Retri at the 7th last with 287,473.55 AVG DPS. If you dont see it by now, Arms doesnt even do the Numbers Retri did BEFORE the buff. On Average of course.
If you look at M+:
Ret is S Tier now together with havoc due to subcreation, which means its the best Melee that actually times keys in a matter of fact. When a DPS Class times more higher keys then others, it should mean anything right? Aso Ret is among the T5 picks now, whilel Arms still Bottom 5 picks an B-Tier to subcreation. When i look at the raw dmg output i can tell you for exampe:
DHT Ret max: 311,993.0
DHT Arms max: 257,537.8
Rise Ret: 244,666.7
Rise Arms: 211,509.7
Waycrest Ret: 298,865.4
Waycrest Arms: 264,586.5
i could go on with this. But i hope now you see the difference - while Arms isnt even on the level Ret was BEFORE the buffs, Ret still got big buffs and was before taken due to his insane Utility and frontloaded damage. Arms is not comparable with Ret at all, its far weaker and it brings way less. Only in the first Everbloom pull it may outdps a Ret, which i wouldnt be sure about aswell.
