I think you misunderstand the term "competitive" and the "Tier lists" related to it.
The competitive scene is determined by the pros. The Tier list is what we see from them: "What do they play? In what order do they pick these Heroes and why ?"

Of course every pros teams have their own styles and draft differently, yet we can see some patterns which in the end describe the current meta-game (= how the game is being played).

No one ask your opinion, this isn't the goal of it.

Now I'm wondering if you really follow the competitive scene:

Since the patch, Sylvanas isn't Tier 1 anymore. It's still a strong hero, but became more situationnal and she's usually picked third or fourth. Meanwhile, Zagara recieved a small buff which make her now the best specialist. Not that far behind is Nazeebo which on the other hand recieved a huge buff (his spiders got the anub's beetles treatment). Some teams like Team Liquid are even picking Nazeebo in the first two when they don't have first pick (and therefore can pick 2 heroes at the same time).

All of this isn't my opinion. I haven't invented any of this. And if you dont trust me, just open your eyes and watch the games by yourself.

Also in your guide for example you got weird things like "Brightwing: One of the best supports....." I mean.... I thought the title also mentionned "Updated for Leoric release". When you update your guide everyday, do you even do anything ? because this kind of things looks pretty outdated to me (Bw is currently the worst support).

If the goal of this guide is to describe your opinion alone how the game should be played, fine. But if that's so, rename it.
