DotA 2 may be coming for your tablets.
DotA 2 for your Android or iOS device sounds far out, but mobile technology is moving at a fast enough that it might be possible.
According to Valve boss himself, DotA 2 may be a possibility for mobile platforms down the line. Speaking to Kotaku, he stated that Valve was already conducting tests: "We were working on getting DotA 2 running on some tablets.
"That ended up being kind of a disappointment. But the good news is that tablets are getting faster very quickly, so I think we'll get the kind of performance we want and other game developers want in the near future."
Though DotA 2 may be fast paced, as Kotaku's Jason Schreier points out, it doesn't require quite as much clicking as does say, StarCraft. Hence, DotA 2 might just work out for the likes of iOS.
The only question then is whether or not DotA 2 mobile players will be able to play with those playing on PC.Then again, whether or not DotA 2 iPad will actually even be a thing remains to be seen.

Really I do not know about your "experience" with the MOBA genre but perceivably you do not understand how MOBA works; any novice Dota 2 or LoL player would verbally bash you for saying how you can misclick the wrong command. Clicking in a MOBA is required as a tool for mainly for repositioning your character while the commands that you give out are done through the keyboard. Which mean, you seem to falsely propose that it would be easier to play Dota 2 on a tablet when you clearly do not have any experience of the game genre at all to know about the playstyle of the game.
