Everyone.
THIS all the way. In my current gameplay, I have 4 OUs, 14 UUs, 1 BL2, 6 RUs, 3 NUs, 14 PUs and 1 NFE and I am doing just fine. My Seaking demolished Samson almost on its own for instance. It is my favorite Pokemon and I have used it succesfully in games and competitively (also in OU battles and whatnot).
[EDIT]: Also, the gym leaders in Reborn give a flying fuck about tiers and kick ass regardless (maybe because of the fields but who cares? Their teams were not tier-tied before we even had field effects). Just sayin. To me, this is pretty delightful. I acknowledge tiers. But I am bored to death with online battling because of that.
In the Pokemon online forum I wanted to use a Vileplume, but apparently Effect Spore is a no-no when coupled with Toxic, Leech Seed, Sludge Bomb and Aromatherapy. But Togekiss with Serene Grace, Thunder Wave and Air Slash is fair enough. And no, I do not need anbody explaining to me why. I just do not see that. Period.
Also in that very same team I had a guy forfeiting (and addressing profane language towards me) because Gallade knew EQ despite having plenty of counters in his team.
