Are my concerns of this dwarfing the resilience change misguided about wow gold? Could we see damage actually increase relative to the survivability of players in season 7?

This question has been brought up time and time again, and I think it is becoming more of a relevant issue in regards to competitive WoW arena as more , better gear continues to be released as more seasons come to an end: is Blizzard being irresponsible by refusing to update gear on the tournament realms about wow gold? Patches come and go and with them comps spawn and die out. But one thing is for certain, Blizzard has never felt the need to least keep arena gear on the tournament realms to within 1 season of the live realms about wow gold.

Personally, I think Blizzard should be keeping the gear on the tournament realm somewhat updated because otherwise they are potentially tainting every tournament held by either MLG, ESL or even Blizzards own to get cheap wow gold. If the game continues to evolve and teams become accustomed to certain gear or even needing particular gear to make their comp effective, it is foolish to roll people back in time to something that is not like live. The most obvious for me in this scenario is WLD in TBC. I could be mistaken here, but I am pretty sure the season 2 gears was very benefiticial for WLD simply because the damage to survivability was much lower than in season 3 or 4, which allowed WLD to be so good at outlasting literally every team and winning by wearing everyone down to get cheap wow gold.

On the flip side, damage could be so ridiculous in the later seasons that certain comps that are designed to outlast or survive important burst fade out entirely.
