Please note that this guide will best serve you on Gotham Heights. The strategies and build I've outlined below are woefully inefficient for Gotham Divided. Please also consider that this guide is a work in progress, and any comments/questions are sincerely appreciated!

Flash Facts
1. This build effectively makes The Flash more of a glass cannon than he is to begin with. While you do have some artifacts that give you mild HP boosts, you will be largely unable to survive more than a few hits. You have one purpose: deal the most damage you can, as quickly as possible, then regroup.

2. The Flash is best utilized in a 2vs1 scenario. Swoop in for the kill or chase down somebody on their last slivers of life. Be careful not to chase too far or too long, as you will likely run headfirst into enemy backup.

3. There is absolutely no shame in running away from a fight. You are The Flash, after all. If you are outgunned, do not try to stick around and fight. You will most likely lose. A great strategy sometimes involves retreating to jungle-hidden backup, then teaming up to take down someone that has been chasing you.

4. This build is very expensive. If possible, use Flash Attack to take out multiple enemy drones/creeps at once. Just be weary of incoming enemy heroes.

5. This build relies heavily on your use of skills. Timing is very important, so keep an eye on your cooldowns in order to maximize your damage.

6. Just because you are an Assassin class, you do not have to get every kill. Getting assists is just as valuable to your team as getting kills.

7. Increased movement speed and skills make The Flash great for harassing enemy champions.

Tactics
Your main purpose, as previously stated, is to kill enemy heroes and drones/creeps as quickly as possible. In order to do this, you are going to need to keep yourself out of trouble.

Your main escape is also your main attack. The Flash Attack is very useful for closing distance, but it has a pretty long cooldown. I highly recommend using the Flash Attack, then following up with a F=MA.

Getting out of danger is going to be difficult. Know your match-ups; certain enemy heroes will slow, root, stun, or otherwise incapacitate you. Using Hyper Vibration will only get you so far, so be prepared to Flash Attack away from danger as well.

Speed Storm is a double-edged sword. It certainly shines in late-game, or when you have a ton of Power Attack from your artifacts, but you will have a hard time doing damage with it early on.
If enemy heroes are chasing you toward your nearest tower/control point, a great tactic is to lull them into a false sense of security. Let them chase you, then Flash Attack backwards, cutting through them, and start your Speed Storm just behind them. This will force them into either engaging your tower, an ally hero, or walking headfirst into your Speed Storm.
​

On Gotham Heights, you can Flash Attack through the boulevards and parked cars. This will be incredibly useful for getting away from melee-based opponents, and perhaps some ranged ones too.

The Flash can create diversions very, very effectively. He cannot commonly take very many hits, so often times your attack damage-oriented opponents will be hunting for you. As such, when an ally is at low health and running away, do not be afraid to jump in to divert some attention your way. A quick F=MA + Flash Attack combo through an enemy hero can help shake attention from your allies. You can get away from enemies faster than almost any of your allies, so having enemy attention is not always a bad thing (with an escape plan).

Match-Ups
There are certain match-ups that the Flash will have trouble with. I advise that you learn these match-ups so that you know which enemies you can typically engage safely, and which ones you are going to need to be extra cautious with.

In my experience, these are the favorable matchups; the ones that I usually will not have much trouble with, and any tips I can provide.
[list]

 Gaslight Batman
Typically, not a very difficult matchup if you engage him 1on1. Try to get to him before he has taken out any creeps, as he has passives that stack and give increased attack speed.

 Doomsday
Very tanky. Consider that most Doomsdays are built for sheer HP and attack armor, though. Engage at half health or lower, if you can. Should be able to outrun them easily even if they activate his buffs. Easy to catch inside of a Speed Storm, as Doomsday has very limited escape options.

 Poison Ivy
Be very weary of her AOE skills and her Root Strike skill (it will knock you down briefly). Also, note that she is great at recovering her own HP, so try not to over-reach.
[/list]
The matchups that tend to go either way for me are:
[list]

 Wonder Woman
Really depends on the build, and how intelligently her ultimate and lasso skills are used. Often, I will avoid this match-up unless someone is en-route to help.

 Superman
Superman is usually not too big of a threat, but can easily catch you while running away and low on HP.
[/list]
