So how can Riot add 9 new items for a temp mode easily?
But can't manage to add items with diversity into the real game? Or change useless items without them sitting for at least a year? Or doing anything in a reasonable period of time?
It has now been proven that Riot can work fast and release new interesting content without having 3 years to work on it, so let's hold to that standard.
In other words, nice job on the new mode, new lore, and all the new quality content you have delivered! Now lets just see that transfer to the actual game on a consistent basis.
