Advice For Level 53+ While Leveling?

[Spinach]

I have now quested SLOWLY and gotten to 55, went back to BRD to try.
Tried the tactic someone suggested with going arms and getting some fast threat with sweeping strikes->WW so I can aoe.
My warrior dies in seconds if I aggro more than 2 mobs without a shield.
Even at 55, and the mobs in BRD are 48-50. Still getting absolutely fucking wrecked. I've just done 5 ghost runs to BRD, now on the 6th after wiping on wave 1 in arena(non-elites died in seconds with healing). I am so frustrated I am actually considering just straight up quitting atm.

The only thing I can do is charge 2 mobs, and cleave them with warr and single target frostbolt on them one by one, which is quite a bit faster than doing the same but as prot on warr, since arms cleave is really good damage.
The questing to get from 53-55 was so slow it was painful.

So atm for me:
Questing sucks ass. 1-5 quests in one zone, then travel and do 1-5 quests -repeat. I'm 45% into 55 on warr, 6 hours played, I am suffering.
BRD is killing my spirit, not only is it slow, every time I try to speed it up I just get rewarded with ghost walks.

I actually don't know what to do as I am not having fun at all atm and can't see a way to get up to 60.
I could get there, slow and steady, but playing in this super ineffiecent manner demotivates me so much. Its fine that I can' get like 80k xp/h like some, I would accept HALF that. 40k or 30k I could do it. Its fine. 5 hours per level would be slow, but acceptable.
Atleast I am getting five chars leveled at the same time as some trade off for being slow. But seeing close to 12hrs per level. fuck me.
I am stuck at barely 15k xp/h atm and its too slow.

I guess I will just have to try to play it safe and cleave 2 mobs at a time with warr and frostbolting 1by1 target and see what my results are. Never pull more than 2 and always sheep etc.

Advice to anyone else if you want to do a tank+spellcleave:
Use a prot paladin, not a warrior. Pre-demoshout nerf it was fine, post demo-shout nerf it is a struggle.
I also think a priest healer would be better than a pala healer in general.
But if you have a pala tank and that actually keeps aggro I guess the pala healer would be fine as you only have one heal target anyway.

If I find a way to effeciently boost up some alts like use the high level pala as prot to boost I will get a warlock and a priest up so I can play: prot pala, hpriest, lock, mage, mage.
I want to main the warrior, but if I am to use the 5 accounts for dungeon farming for gold etc. I want to have a easier team to grind with.
If anyone has any advice on boosting lowbies I would love to hear it.

Edit: I guess if I get a Force reactive disk on warr etc. maybe stuff could work out, that will be my first plan I guess.
