Did anyone try it?
They seem to open the map for people the last few days, every day for a few hours, and it's an incredible blast.
It's completely different from Summoners Rift or that forgotten 3vs3 map, and it's amazing.
A match never really takes longer than 25-30 mins, more like 20 most of the time, and you win by holding nodes. The more nodes you have, the faster the opponents time runs out, so the goal is not to kill a lot, but to make them lose their nodes, taking you ever closer to that sweet win.
It's intensively fun.
On EU servers it was on from 5 PM to about 10 PM, UK time, both yesterday and the day before.
My favorite champion to play here is amumu. Start out with boots, grab either a MR or an Armor piece, then head bot, while the others grab middle and go for top, then build your items into Sunfire Cape and Abyssal scepter. As Amumu you do magic damage, which is what Sunfire does, and Abyssal gives mpen, which helps to make it hurt more. With sunfire you also get a good chunk of armor and health, while the Abyssal Scepter gives you MR and AP. Top it off (if the match takes this long) with a Rylais, for more HP/AP and slow goodness (your tears will perma-slow everyone around you), and it's good game.
Tons of fun.
Can't wait till they fully enable the mode.
