The results are not shocking at all.
Tier-Sets brought only casual players at a disadvantage and main-raiders with lootpriority in the first weeks for 4-set-bonus had each new tier a huge advantage after the first 1/2 weeks. Casuals and non-raiders had to live with broken specs, because many times the set bonuses were the fixes for the whole tier.
And the same people with the perma disadvantage for many years vote for YES, because reasons.
If blizzard would implement every casual player whislist, there won't be any casual players left playing this game.
I don't mind propper transmog sets each tier/theme but why would you want a system change back to the old, where most of the voters here did not even benefit from at all.
