I'm not sure we can call the gear nerf as "negating the awesome pve experience". Let's be real, the PvE experience is fairly miserable depending on the activity :
- farming WoD dungeons ? I mean we all are more or less bored/done with it, not that they're bad dungeons but doing hundreds upon hundreds of runs will get anybody tired of it ;
- gearing as a whole ? Epics will still be slightly better for non TBC socketed gear spots but marginally so you can get good gear very quickly and have some decent socketed gear fairly easily -farming for gems still is a bit of a pain but warbank will be huge for this, one alt with JC and you're good to go-. Warbands also mean faster enchanting, alchemy one one char so a huge plus on this point
- farming for collectionism (achievements, pets, mounts, xmogs whatever really) ? There I can see why it would be worse, mindless grinding is better when done faster (like Island expeditions for instance). That said, the fact that wewill be able to share some currencies and at some point reps most likely means you won't be locked on a single character for farms which -in my humble opinion- is a nice plus and outweighs the lower power level con ;
- questing ? It is quite possibly the less interesting part of PvE as of now which saddens me quite a lot. If you aren't doing the "gearing while questing" gameplay where you just start a character in their starting areas (not Exile's Reach) and go around, doing quests, getting some gear slowly or giving yourself self-restrictions when it comes to ilvl, you basically one-shot everything, can aggro dozens of mobs and it is very uninteresting gameplay-wise. TWW's gear nerf will make things -a little- more challenging (at least not being basically in creative mode) and that is a good thing, especially considering that anyone in dungeon blues will still be strong enough to have no issue at all ;
- travel ? How about flying? Sounds great and oh wait...
We'll have to wait, changes will happen and we're not sure how TWW PvE will look like.
Tbh I have good hopes for the talent trees, the Warrior one looks great, we won't have to waste a talent points to get
https://www.wowhead.com/spell=29838/second-wind and who knows, maybe we'll get
https://www.wowhead.com/spell=184367/rampage and
https://www.wowhead.com/spell=81099/single-minded-fury back.
One can dream.
So yeah I think TWW PvE looks great so far don't stress about soloing dungeons, the new ilvl 84 seems to be around the current ilvl 54 so we'll still be plenty strong and dungeons won't be an issue
