Reworks
Seriously. Take Alistair for example. The assassin rework patch came and that champion got a mini-rework. I don't know if I am blind or living in a cave, but Riot did not mention anything about it for a while. I figured out it when I auto-fill a support and took Alistair. Also again, I could be living in a cave, but did anyone knew about the Kindred rework this patch (7.11). Her new passive increase her auto attack range and they rework all of her abilities beside her ult. Her Q gives attack speed and not attack damage. Her W is magic damage now. Her E is missing health damage and not max health damage.
I'm sorry if I sound like an idiot for not knowing, but I barely knew these rework happened and I would like to find a way to be alerted to them. Beside, aren't these pretty big to someone maining these champions?
