The Alt Plan...

To keep myself occupied during the interminable wait for Legion, I have come up with a plan! 
I do like having a plan.

I have my Shaman (and now Mage) for main raiding.  He also does all the other stuff that comes with being a main... rep grinds, transmog, etc.

But my main has been doing all that for a long time now and needs minimal attention between raids.

So... plenty of time for the plan!

The aim is to have the Legendary Ring,  4-set bonus and Archimonde trinket on 4 (so far) more chars:
Rogue
Hunter (will skip the trinket)
Priest
Paladin

Then have a full run, hopefully on Heroic, with all of these OP items to see how they perform before exchanging them for some quest greens in Legion.

Rogue:
Seemed like the best place to start as I can already play it. 
Subtlety is supposed to be the go-to single target spec though and I was least practiced on that as it was traditionally considered to be the 'PvP spec'.

The reality of raiding in HFC though is that there aren't many pure single target fights so Combat is almost always better anyway. 
Given the different stat priorities, it's not really viable to gear for both on an alt so I plumped for the more versatile (and much simpler) Combat... Blade Flurry OP much?

Already up to the Tome-collection part of the Legendary, it didn't take long to complete the ring and the greatest difficulty seemed to be getting into pugs as a melee dps.

Definitely the most advanced along the plan with the ring, 3/4 tier pieces and 711ilvl but the amount of time spent trying to get into pugs is quite tiresome.

Hunter:
Barely touched since hitting the pugging wall back in BRF but the garrison and shipyard have kept her plodding along with the ring, just the Tomes to collect.

Gear is probably the biggest issue now, sat at 680ilvl, but a few trips to the jungle should help bridge the gap (and there's always PvP... yeah, right)

Hasn't actually set foot in HFC yet and probably needs to spec out of Survival before I try any pugs.

Priest:
A mixture of Baleful, Crafted and BoE gear has taken the priest to 691ilvl, ready to jump into some pugs but not actually done any yet.

Based on LFR experiences, which admittedly doesn't tell you much, it's incredibly er... spammy to play.  Throw PW:Shield on anything that looks like it might take some damage at some point, fill with Penance and Smite.

I think I need to look into it a bit more, surely there is more to it than that?

Furthest behind on the Ring, still working on the Runes from BRF.

Paladin:
My white whale.  My Eleanor.  My unicorn.

Combine a lack of confidence as a tank with a fear of pugging and this guy struggles to make it out of his garrison.
One day, before I finish playing this game, I will be a decent tank.

That day hasn't arrived yet though  :-s

So far he has ventured into Hellbreach LFR twice and Halls of Blood LFR once, none of them were pleasant experiences.

The garrison means he only needs Tomes for the ring and Tanaan/Auction House has taken his gear to 692ilvl. 
Getting the tier set and Archi trinket though will require some actual raiding at some point.

I'll let you know if that happens... don't hold your breath.
