Just like DOTA, only as a FPS
The game used to be fast paced, now abilities have longer cooldowns and everyone moves painfully slow. Every thing's health was increase, and damage decreased, so fights are much slower. Tower defenses used to be build and repaired by players, now they are pre-build and irreplaceable. Maps used to be larger, now they all look and play the same. Although the redesigned matchmaking results in full games, it takes too long (over 5 minutes to find a game)
Very little game currency is earned in matches, and real $ prices are just absurd, so you'd better hope your favorite champion is part of the free rotation.
SMNC is not bad looking, and it plays decent for a free-to-play, but so much of what drew me into this series has been replace with generic Dota cloning.
It's free though, at least give it a try if you're interested.
