The new map looks great, but I'm not too fond of the game play. I really don't like the capture spots, it does feel more like dominion than a 5v5 match. This is a totally different experience. I'm not a fan of dominion and usually don't play 5v5 because they take almost an hour on average.
Widening the 'bottle neck areas really prevents the idea of a comeback. It seems like once you are being pushed, you'll never be able to make it up, especially if the other team claims both the points in the middle and gets the double buff. In my opinion, once you get pushed you'll never be able to come back. I foresee A LOT of surrenders after losing your first two turrets. The one thing I liked about the old TT is it was NEVER over until you lost your turret at the NEXUS, and even then, you still had a chance.
Having to run around from the spawn point to get to the nexus to defend it is also a pain. You used to be able to defend straight when coming back alive, now you have to run all the way around and that could be the difference between saving your turret and losing.
Also, I REALLY dislike taking away the upper jungle. That was great for escape routes, farming.
I'd personally rather have the old TT with a graphics upgrade.
Pros to new map: Spider and graphics
Cons: Everything else.
