(Apologize for my awful English)
Let's talk about Vertigo, i think its the worst map of the game for many reasons.
One of the main reason is the fact that Enforcer, GS and Harrier are way better than any other role in this map. Because the lines of sight are way too big, there isnt so much walls etc. Juggernaut is almost useless on this map for example (even if i think it isnt only because of the map). Ans its a really hard map for Wraith and Sin.
The Hitscan long range classes are completely free to shoot everything they want to shoot.
So i think the map need a lot of rework, more walls etc; but i dont know exactly how to change it so much.
But it isnt the only reason imo.
The place of Battery/Uplink in middle is bad i guess. Because all long ranged character are free to shoot anyone on it. And because the health station is way too close from the battery.
I think the battery should be bot-mid and not top mid. So it would be easier for Juggernaut to place a useful wall and a little bit harder for GS etc to shoot at people on battery. And if the battery is bot, it takes more time to go to the health station top, so you cant easily go in/out as you want.
Then, in this map it is way too easy to defend for a lot of reasons.
The first thing is : the spawn is too close and you can shoot at enemy taking battery from your spawn, its a shame imo. You can even see if an enemy is flanking and healing himself in health station behind everybody, making the defense easier and the attack harder.
Is this really normal and balanced ? If someone dies, he reappears really close and can get into the battle really fast.
One of my thought too is the health station is too close from the battery, and not safe at all for someone attacking in the back. Compared to other maps you lose nothing if you take the time to go to health station in defense, you can almost stay close and shoot at enemies at the same time. And when you attack you cant even be relax when you are into the station.
So one of my first suggestion is to move the health station at this place :
And to move the 2 medkits where is the health station actually. The health station would be a little bit further for the defense, and safer for the attack. So it would be easier to flank.
Then maybe add a wall where i drew it here :
Its just to not be able to shoot at people on battery when you are in your spawn. So you have to go out of your spawn and you take a little bit more time to come into the battle.
Then it isnt the biggest problem but i feel like there isn't a lot of flanking way to go "behind" enemies, especially compared to other maps once again. Cause one of the side is completely blocked by the enemy spawn.
With Sin you can grapple here :
So you land here :
But you are just in front of the enemy spawn and health station so you ve got a lot of risks by doing it. Maybe removed this door to go away of the spawn :
Just to be a little bit more safe. But i guess the flanking routes arent the biggest problems, especially if you move the health station where i said it before.
Actually even if the map looks cool, i hate to play on it. And i hope you are going to make a lot of changes on it.
Hope you understood my English !
Good bye !
