Stop making everything account bound. >_<
Mounts and pets were find and achievements were a nice compromise but if everything keeps getting combined, then there's less to do for those who don't like max level end game (dungeons, raids, etc).
If reputations are shared then make it be opt-in.
They had a GOOD solution already in Wrath: Tabards for rep in dungeons and badges bought with badges.
The only problem with that Shae is that people were forsaking the actual world and, instead, choosing to run instances ad infinitum (which IS a choice as is questing). However, by forsaking one option for another, it diminishes the effort both physical and financial Blizzard puts into content.
On the flip side of that coin, we have to ask how do we create a middle ground? I feel that we're, as a whole, in this discussion are on to something REALLY good here. With a possible Partial Account Bound Rep and tabards which are gated by rep standing i.e. revered (going to exalted may be a bit much) but boa, this could lessen the pain for alts and keep people invested or even INTERESTED in BOTH the tab gains and actual daily gains.
Which leads me to THIS question, would doing dailies have to necessitate negating the tabard gains and vice versa? Personally, I'm on the fence about this. On one hand, I LOVE the idea, on the other....I don't want to run out of 'stuff' too quickly. So, what do you think?
