Riot wasant happy with how strong locket was already, they had to make it even more ridiculous.
Now you can easily get 1k+ shields late game with it...
"but squishy supports arent as likely to build BOTH redemption AND locket!!!".
They still do nothing changed, all that changed is that now tanks (not just supports, tanks on every lane and even some bruisers/juggernauts) can now build it and have a locket that is as powerful as the old combination of locket + redemption.
Seriously pressing 1 key for a total of over 5k effective health to your team that is instant? What the fuck riot? How can you possibly do this, locket needs to be reworked at this point as if you try to "nerf" it again we might end with 2k hp shields.
And ppl wonder why assassins and burst champs are shit atm, how can you deal with a team having multiple of those actives? And thats not even counting the average tank and support kit full of peel and other shields (oh hello lulu/janna/thresh).
