That Ardent Censer passive will have to have a nerf. You guys already mentioned about things like a four man Thresh shield. What scares me more is that it offers six seconds of attack speed buff.
Sona's W is a 7 second cool down. Everyone to have all the attack speed, all the time. Not that I would be upset about being able to use more waifu. Still, passive would probably need a cool down or a limit to how many people it would work on. I mean Thresh need more utility, right?
Bit late, but liking the new VU for the rift. Daft as it sounds though, I wonder if it will be a bit more taxing on PCs. League is so popular I bet a lot of people play it on, to coin a phrase, shitboxes. Not sure how happy they would be if the system requirements went up - though I suppose lots of options to tone down the detail.
