I guess its the same thing for brutal gear. Last season we had like what ?10 teams in 2s, 2 teams in 3s, 7 teams in 5s that were above 2K2 rating. So it would make some parts of the s4 gear still rare. Even thought the season is out for 3 seasons ..... Now For pvp, the real issue is the imbalance in pvp (damage wise), with the example of warglaives, why would rogues have "acces" to legendary weapons and not everybody ? And by acces i meant from coins, whatever the price is. And dont get my wrong i have nothing against any sort of shop, but atm it is just creating imbalance in the game.
To be honest i could rant a lot more on how low priced s4 gear on a store could create some sort of toxic atmosphere; if anyone is interested!!
