Sad that u not played before Legion(I guess), because after Bfa Legion is the worst of all. Wotlk was the peak imo, because we had rating based pvp gear from VENDOR. You had to grind out the honor gear, then if u was good enough player you was able to buy for example the Wrathful shoulders at 2,2k cr(I only bought my daggers at 1850 and i was so happy!). The good players loved this because they felt the worth of playing since they become stronger in ilvl(gearscore xD), and of course damage. After Wotlk Cataclysm was a huge fall because they first removed the rating based gear, only the weapon was stronger above 2,2k, then in Cataclysm again they removed the stronger weapon too. Still Cataclysm was a very good expansion in pvp, i played with several class and i loved very very much. MoP was very good too, sad that they started to change again the resilience for “fix resilience, pvp power” just to favor the pve clowns after their downfall on 5.2 Isle of Thunder. Wod was miles better then Legion, and ofc Bfa , but the prunning and trash pvp removed a lot of player from the game.
Now what is the reward? A trash title/tabard/cloak the worst enchant and a terrible mount(i loved the legion one so much it is beautiful).
