Sounds like you believe this map is new?
Many would argue that
Tides of Blood O is a completely new game compared to
Tides of Blood N, but that is besides the point.
This has been under development for years. Just look at the first post.
The amount of players who play Tides of Blood are less than 1% of the players that play DotA Allstars.
Tides of Blood is a fan-based game, where
DotA Allstars has been a major BNet hit even since
Tides of Blood N was out. The point being that there is far more traffic for a game like
DotA Allstars and as such it requires a lot more to maintain it and keep its players happy.
I'm sure if you were to look at the statistics of how many games of
Tides of Blood have been played as to how many games of
DotA Allstars has been played the ratio would be astronomical, you can't even compare the mechanics of a game like
DotA Allstars to a game like
Tides of Blood, doing so just proves that
DotA Allstars has had such a great impact on
your life that you feel the need to lesser its accomplishments so that
Tides of Blood shines more.
The items in
DotA Allstars are like the unit upgrades in
Tides of Blood, if you don't know them well then you're going to lose. As it is caster upgrades in
Tides of Blood are completely over-powered and if you're not investing in unit upgrades then you will most definitely lose, at least in
DotA Allstars you don't have to know
exactly how to play in order to not get completely obliterated in the game. It's not like
Tides of Blood is balanced either, but neither is
DotA Allstars.
In my experience, playing with average public BNet players, every single
Tides of Blood O game I have played has been a prolonged waste of my time. It always seems to end up with one team winning by a landslide over the other, with absolutely no possibility of returning for victory. The entire game is dictated by how well you know the game mechanics, and how many things you can abuse in the time it takes to play the game.
