I'll start by saying I am a big MOBA fan and I've played all of them, mostly DOTA2 and HOTS where I've put thousands of hours into.
I've already played about 500 games of Pokemon Unite. The game is refreshing with simple mechanics and new idea of play. Though it falls short big time because of greed and Laziness which makes it the worst MOBA ever.
First of all the unfair items which are P2W. You put money into upgrading the items to lvl30 and you get a noticeable advantage. Once they nerf that item which you put money into you need to pay more to upgrade another one that fits better. This is by far the worst system in any MOBA it makes the game very unfair.
There are also some pokemon that are very very broken. As of this month I am writing this review. Gengar is unbelievably broken, the damage on that hero is unreal. He can kill 3 pokemons solo even when standing on the Goalpoint and getting shield boost. I've lost so many games because of this mega broken pokemon, and my winrate gone down much because of this...
The matchmaking is pretty bad too. I don't like playing with a stack and I also don't want to play against a stack. I very often find myself matching against a stack even though I search solo. This is unfair and unacceptable.
For example in HOTS when I search a game solo, I get matched mostly with solo players. Only when it takes a long time to find a game, there is a chance I get matched with or against a stack. But in pokemon unite, very often I find myself matching against a stack.
There is also only one Map which is already very empty and boring. There should have been many different stadiums to play in, like there are different maps in HOTS with different objectives. It makes the game more fresh and fun.
DOTA2 have 1 map because its very big map and have too many details and tricks.
In pokemon unite you can't live forever with one map it does not fit the game. Nintendo being very lazy by not providing more maps. Focusing instead on greed.
By the way the price of upgrading items and buying new skins for pokemons is ridiculous!
In conclusion this game is not worth the time at all. Me and all my friends already tired of it and no one I know whats to touch this game anymore.
