I think it's got some interesting protentional going for the idea. Seems like they've made a career out of taking game-types and putting a sort of improvement/original take on it. Moba, TCG, Autochess, FPS, and at some point a fighting game and a/rpg? I quit LoL years ago(top laner overhaul), but iirc they were also doing a story overhaul at some point and Marvel comics got involved to help flesh it out with supposed comics in the works.
I just know there are quite a few factions in the lore, some obviously intertwine with each other and others more than likely unplayable but my guess is they're gonna rip Warhammer Online's original concept before it released. I'm just wondering if they'll keep to the trend of f2p and market the mtx or mix up with some sort of optional sub with perks. They'll be playing ball with MTG, and presumably wow/ffxiv are not dying anytime soon.
