Paladins, for the "Look at me I'm the perfect hero guy" feeling and aesthetics (flashes, bubbles and sparklings everywhere)
In the second place I'd say druids, just for the huge button bloat.

This is really hard for me to answer because technically my favorite and least-favorite class is Warrior. I used to love everything about War. And I still love the look, feel, and utility buttons.
But... that gameplay. Ugh. Arms is... eh, Arms has always been the weird cousin no one invites to Thanksgiving. But Prot... Prot was absolutely destroyed (for me) in MoP, it's boring and tedious and just not the same spec it was for like 8 years. And Fury's conversion in Cata into a metronome spec timed around Colossus Smash makes me want to scream and shake the monitor in boredom/frustration.
Basically, the changes to Warrior in Cata/MoP resulted in a class I both adore and love, yet simultaneously absolutely loathe and never want to log in again.
Monk - just cant get the hang of them. Too much flashy animation, not enough substance.
Paladin - everything they do, they do in a boring way. Especially ret and holy. Don't have much experience as prot.
Mage - most boring caster. 1 dimensional, terrible lvl 90 talents that break the entire class, just completely meh.
DK's for me, tried a couple over the years, just don't like them at all.
Loved my alt prot pala back in wrath/cata, and I hate what they did to them in MoP, it's sat at my farm and does nothing but plant stuff. Hits like a wet noodle even in full Timeless...
Shout out for rogue too sadly, always loved levelling my rogue (sap, pickpocket etc) just never found them fun at endgame
Warriors in PvP are like small hyperactive children in a candy shop made of bouncy castle.
Warriors and monks are pretty boring. Warriors don't have any appeal to me, just play a pally! ;p
And I don't think I ever gave monks a chance...
Sweeter than yo mama's apple pie.
I hate Shamans. Dirty Horde scum! Take your totems and shove them up your elemental butts!
voted druid & shaman. havnt leveled those 2 classes past lvl 15, while having one at maxlvl (at the time i levled them, ex vanilla i lvld a warlock to 60, and havnt played it since)
For druids, i just dont like that you can use both rage and energy - cmon is it a rogue or a warrior ?
Rogue and paladin.
Rogue: To be the most effective, it felt like I had to stealth to start everything, meaning slower and more deliberate. Or, you can not stealth and just walk in - ala a warrior. I was going to use my free 80/transfer on a rogue, but then I realized I wouldn't learn how to play him and when I do play mine (low 40s), I start off slow and then easily end up as #1 damage in a dungeon.
Paladin: Just... too righteous and alliance feeling for my tastes.
rogues. fun to level in pvp but at max level i only pve and they are extremely boring then.
Death Knight's...
I just have hated them since the beginning of wotlk.
Boring mechanics, boring gameplay.
I never played priest,druid and mage in end game. I got them in leveling process but they are just not my class type.
From which i got and played a little in dungeons/lfr etc. i think my least favorite is monk,warlock,shaman,death knight(which is funny cause i raided ds as uh dk). But tbh only classes that i really like to play after level them to 90 is Warrior (obviously because it's my main ) and Hunter. I play a litttle on rogue and ret paladin but not so much.
The only class I've quit out of pure boredom was a pally.
The constant waiting for that 1 attack to come off cooldown drove me nuts, felt extremely sluggish.
Truth be told, that was a loooong time ago though, maybe they've had a big overhaul and are fun now.
The other class that has ( and still is ) taken me well over 2 years alrdy to lvl is my sub rogue.
Everytime I start, level a few levels and then leave him again,...currently he has been stuck at lvl 78 for well over a year now.
The building up combopoints, only to see them go to waste because trash dies so frikkin fast these days with all the people in looms just annoys the hell out of me. Just always feel like I can never get the most out of the class.
In PvP I can only get people burned down to 10-15% health in 1 single stunlock, only to have them turn around and whoop my ass :P.
I guess it's just not my class. The low lvl questing as sub was sublime though, actually planning which mob to stun, which to distract and then quickly kill another off and vanish into thin air again. One of the more immersive gameplay styles in the game at low lvl's.
Maybe I should give him another chance
Priest. Always thought they were a pain at low levels and not a major fan of a class with its only DPS spec being heavily DoT related.
Never could get into a mage.
