Mmm not sure why /u/TheGod2eZ seems to be so antagonized. Hell it's almost as if he's Exil! (nothing too major against him either anymore. We all start off as cocky little dickies if we want to get somewhere)
Personally I prefer to start Q even just for CSing and the flexibility. But there definitely is a trade off between getting off a free good level 1 trade (most of the time) and allowing safe farm early with little jungle threat and getting lv3 before renek (usually enemy gets 1v2 when pushing but you often get lv3). You have more options at that point:
Whereas in the early pushed lane he takes the initiative where you'll also have to be highly wary of the enemy jungler. Apart from small trades at tower you'll have to sit back and wait for the huge approaching minion wave. (where renekton could've healed back significantly from level 1 trade)
tl;dr These aren't set in stone, just one possible outcome following early decisions but I want to highlight the viability in different strats. (idk what's optimal myself) Also there's no reason to be so spiteful? He's not forcing this playstyle down our throats. Yes he speaks with a fair amount of authority but not nearly as bad as these comments:
"Why don't you don't this, you should do it this way." --> aggressively upvoted (which is fine)
"Opinion" (Trice) --> downvotes
"You're a fkn dumbass" (In a more subtle taunting way) - Not that ok.
tl:dr Let's all be nice to each other :). Nah but for real. I'm not defending him just for the heck of it. I reakon he definitely has some viable opinions that are too readily dismissed.
