Hots is a nice game, but that's that..
Not overly punishing to nabs, and as a result most people seems content playing it "so-so" without stepping you4 game..
Lol and dota2 instead put you in a brutal position: your under performance will most likely be the loss factor?.
In hots your bad performance at most is an issue, but with shared exp, unless you're TERRIBAD you can't really cause a loss on your own.. In the other competitor if you feed your lane.. You grow monsters
Other thing hoTs is generally slow and they might want to add some new mechanics here and there to apice up thing..
Ap carry duel can ve brutally fast, in hotS instead assassin 1vs1is rarely about who engages better, lest One is a stealther..
I may sound biased, but even though i appreciate hots, as far as i am concerned it's the lame cousin of the moba genre when compared to notable alternatives..
If the chars were not SO fanboys-food, it would easily be on smite-level or even below that, imho..
