This dated system where every patch or expansion makes everything in the previous version obsolete is a dated mechanic.
I will edit the statement below to be understood by the general wow community
Destiny Example
In destiny you acquire legendariesyou can only equip 2 at a time every big update increases the ilevel but you don’t need to throw away your gear since if you find a 255 ilevel pants you can infuse it to your 212 ilevel pants making it 255… so if you know you like a lot of Haste , you can keep the armor that gives you haste. This infusing system works with legendaries as well… the biggest reason to actually change your gear is these updates will bring legendaries/Epics(raid items) with new effects offering new playstyles. Some of these new effects can be specifically powerful in that raid… meaning you’d wear different gear to raid then you would for pvp.
Elder Scrolls online Example
In elder scrolls online the level cap is 50 with the ilevel cap being 160cp.
When new updates come the zones are added more for progression of a story and again offering new items offering more playstyles. You could literally buy base elder scrolls online for $5 and still be viable in an end game setting with a base set.
Sets are the biggest way elder scrolls online incentives you to change your gear… you’d have a set for solo content, one for PvP, one that is just a fun gimmicky build (Shockadin)
So why doesn’t WoW do this?
WoW community already does old content for mounts and transmogs… and I personally feel like blizzard could create some truly fun sets.
Way WoW could use this set theme
Like a legendary Rogue helmet that allows a rogue to have 10 combo points… which then allows you to build to 10 then use 2 finishers.
Or a legendary Paladin chest piece that when tied to a legendary weapon usually used by shamans allows Paladins to play a gimmicky Shockadin build that holy Paladins can use in solo content or to meme in BGs.
Just…
I understand change is scary but I feel like this system of new, new, new and throwing out the old, old old is what blizzard should look to remaking instead of focusing all their development on Torghast… the next expansions new gimmick.
Tl;DR: Nerf Demon hunters and give Rogues/Monks double jump but demon hunters keep slow fall.
