Your post is full of flaws and your opinions are really one sided as a warrior point of view, so i didnt really bother with serious reply.I just found it hilarious that in your Wotlk example to show how easy it was, one of the teams were AFK. In your post, you compare how easy melee cleaves used to be compared to Wod, but you don't bring up how you died during a shadowfury stun as a melee in Wotlk. In fact you only bring the good parts how you were able to do unhealable damage and kill targets during lockouts, but even when melee cleaves were on their prime ( assuming Woltk) you got countered by wizard cleaves. You argue that this isn't possible anymore and therefore melee cleave skill cap have raised, but if you check the video OP posted, you can see that this isn't the case. This kind of playstyle have been carrying people to success without any coordination or skill. Just because warriors aren't FOTM at the moment and aren't able to do that, it dosen't mean that the playstyle for other melee cleaves have changed. If anything warrior skill cap have raised in melee cleaves, but to be honest it was close to zero to begin with (I have only been 2k this season, so my understanding of the current patch is clearly shit, so based on your post i assumed that warriors are bad in melee cleaves). Also as someone, who did level DK in s6 and got R1 as Dk/Ret/Druid with t1 weapon and without any real voice communication. I never really understand when people talk about skill cap of melee cleaves. Only thing which require any brain is to understand the strenght of your comp and abuse that. Wizard cleaves are able to succeed with every little effort compared to some MCH's aswell, so i really don't see the point of arguing which requires more skill.
Also i know that you have mad respect for Lolflay, since you are even using him as argument. But let's be real, there's a reason why flay haven't changed his character in AJ past two expansions ( and it's not because he haven't been playing (washed up) ). This is coming from a guy who has played with him in both expansions. In the end its personal preference, what you rather face and personally i rather face wizard cleaves than melee cleaves.
tl dr; melee cleave & wizard cleave players are scum, only rmp players are good, only s5s6s7 R1's matter, lolflay is a fucking retard, fuck hunters, delete dks, bring back mana burn, buff resto druids
