Legend of the Poro King is so much more fun than the original ARAM, it's so much better that you can choose your champions and also be able to ban the usual overpowered picks that ruin your day in ARAM. Added to this being able to summon the Poro King and use him to your advantage brings more strategy and flavor to the whole experience.
Would you guys like to keep the mode as a dedicated, permanent mode?
Eh. as with most of the rotating game modes, it gets old after a while. And while you can ban out some of the stronger aram champs, you still usually had a lot of the same champions in your games, and it gets stale.
in 50 games, I had:
11 
19 
10 
13 
10 
15 
24 
25 
14 
And plenty of 
without that much of anything else.
The lack of randomness severely hurts the longevity of the mode. The simplicity of the map itself combined with Riot's persistent lack of support for non-SR modes means that LotPK would quickly become stale and stagnant in terms of champ picks.
I really dislike Poro King, because it is too similar to ARAM and it takes so many weekends of the RGM.
If you were to make it permanent instead of ARAM, it would make sense to me.
And I would be glad since I wouldn't spend every friday asking myself if the next rotating game mode will be Poro King or Poro King.
Heck, maybe I'd even get to play URF ? Or at least anything else than Poro King ?
Every game seems to boil down to picking a long ranged/CC-chain, burst/poke comp or losing horribly. Assassins (and most bruisers) are pretty much useless on this mode and there's little room for experimentation or strategy. Just lock in a tank, caster support, or a control/siege mage every game and enjoy your easy wins.
After like 30 games, you will guaranteed see the same champions every game, regardless of bans. Poro King somehow finds a way to be even more braindead than Nexus Siege and Hexakill, which is an accomplishment. This game mode takes everything that's currently wrong with LoL and concentrates it into a narrow, attrition-based map.
