First off I know what MOBA is, not seeing your point I'm bringing up a pointless point.
2nd clearly you're upset about them recycling old ideas. Ok. Name one game out now PC or Council wise that HASN'T been recycled and renamed. Who gives a crap , I dont care if they make a game mode that looked like Mario and called I'd league land and had yasuo jumping onto sweres.
It's fun, it's better than the old version, it's on a game we all play (clearly) and I like it.
As far as the rest YES, I loved ascension, and this other mode before ascension they threw under the rug where you fought for control over towers. But I like TFT, and so do others, BUT I will say I don't like the idea of ranked TFT.
The reason I like it now is because I dont have to LOSE souly because my teams throw, if I lose or win it's partly on me partly on rng. I'm fine with that. No one's toxic, no flaming. And I enjoy that.
Not to mention there's not 40 people dodging making your 1 minute wait turn into 10.
