Super-duper-complicated.
I would play something that is classic but fundamentally different: a dungeon dweller in which you queue, enter a dungeon and get teleported, your level, gear, abilities set appropriately, eating & drinking is an ability (fine, actually, 80 each is enough, there is no need for loot - but wait, that’s unfun), however, it’s challenging, I mean from there onwards it’s the same as is in Classic.
Outdoor leveling? Nice, but it gets a little slow in the second half. And really, I’d like to progress to BC indeed.
The BC world has fewer elites, some rescaled. The talents are a bit better balanced, although the power spikes are at different points.
Dungeons? Sure, but spamming for hours on end to find a group…
Raids? Really shouldn’t do multiple expansions in paralel.
PvP server? No way I’d play them. For most, the other way around.
So really, having a character on a Classic PvE server sounds like an option to just fool around once a week or month, away from the usual set of characters, enjoying the rested bonus.
Ultimately, an XP lock at 60 on BC servers and/or all-the-way Chromie time on retail is essentially the same experience, with a bunch of little details I could ramble on about.
No.
Not against it, simply it’d be like my own little servers. Oops, didn’t log for four years. Oops, only played 3 hours in seven years.
Also… I’ve done so much leveling, I’m not sure I want fresh. Economy is one thing, but really, another 120-240 hours just to have one character, or yet another altoholic combo with a bunch of level 35 characters over the course of a year…
