Foremost of all claims made by
proponents of DOTA 2 is that their game has a higher skill-ceiling
than League of Legends. I believe that one of the primary reasons
for this claim lies in the fact that DOTA 2 champions scale more
extremely and thus end up dishing out more damage -- meaning that one
false step, or a champion with a slightly better combo, is more
likely to instantly kill you (or your entire team). But this doesn't
make the game more skillful, it makes the game less fun. Yes,
mistakes are punished more harshly, but this is because the champions
in DOTA 2 are generally much more powerful and it is easier for a
champion to snowball and nuke an opponent down more quickly. This
makes comebacks less likely and that, also, makes the DOTA 2 less fun
to watch and play.
The next most common argument regarding
skill is that creep denying is more difficult and thus more
attractive to more capable players. But really... creep denying is
just glorified farming -- and it's hardly the most intriguing part of
any game in this genre. Not only that, but creep denying delays
interaction between opponents in a lane. This is because players can
stick closer to their towers to farm. But, at the same time, if they
are both competently denied, it delays interaction because leveling
becomes more difficult and items take longer to acquire. And then,
both the champions of a heavily denied lane probably won't be able to
contribute very much to team fights in the mid-game. Because of the
need to stay in lane and farm, most DOTA 2 players admit that the
first 20 minutes of their game is much slower paced than a League of
Legends match (which often has a level one team fight at the red or
blue buff camps).
