Hello everyone, I am Bushel Firesbane, and this is my first build here on mobafire so please don't kill me :).
I am mostly just testing out the features at the moment to see how the site works - but I hope you enjoy the build anyways.
Fast Ashe is a build of Ashe that focuses on slowing the opponent and, more importantly, being extremely fast. It was a tough call between cleanse and flash, but... flash is flash and is completely overpowered.
The goal is to absolutely not feed, by being able to get away from everyone extremely fast through sheer speed, and at the same time run down anyone that tries to escape from a gank or teamfight, allowing your team to do the most of the damage, but dealing quite a bit of damage yourself.
Armor penetration is a good thing, and bringing that into the fold helps you a lot early game, simply to have some exist - because the small amounts of armor everyone has at the beginning are the most significant due to the somewhat logarithmic growth pattern of armor. This is why we have the marks - the only reason we don't have the quintessences as well is due to the need to increase movement speed, even by that five percent - at the beginning of the game.
Next we have dodging which is a pretty big deal when you are trying to escape - we put that under the seal's jurisdiction to handle.
Lastly, we increase attack speed to ensure that we can get as much slows off in a short period of time as possible - this falls to the glyphs.
There are four very good summoner spells to use with this - but I recommend moving around the masteries a bit if you deviate from what is my preference.
Flash is godly - it is also awesome, and can be used for pursuit, ganking, sometimes kiting, and escaping - or travel if you are incredibly desperate
Ghost can be used for escape and for pursuit, sometimes kiting, and it is great for travel if you need to get somewhere pretty quick - I choose this over cleanse and exhaust simply because this build is very heavy on movement speed so the extra percent-based boost is quite powerful.
Cleanse is an effective alternative, because the main reason you will die (if you do) will be because of people stacking slows on you, or stunning you when you get too aggressive, fail to ward - or face check bushes (don't). Therefore, popping Cleanse can get those off of you when everyone believes you to be doomed - can sometimes also result in your pursuers getting a little too aggressive and getting killed by allies.
Exhaust can also be handy for pursuit - it is not that great for escape due to it being single target - which is THE reason it is not the recommended spell for this build, because whether you are ganked by 1, 2, or 5 - you need to escape.
if you do not use flash, i recommend going with cleanse because combining that with ghost will get you out of bad situations really quick and your opponents might have a hard time realizing why.
if you don't use ghost, I recommend going with exhaust - and to play slightly more aggressively - because the combination of flash and exhaust can take people off guard and can land you or a team mate a kill pretty well (p.s. I recommend using that combo when you have at least one person to support you)
Pros / Cons
Team gets fed more
Heavy Slow ability
Less Kills (not pure damage or crit focused)
You will need support (don't engage more than one enemy alone - and be cautious engaging one)
Face checking bush will kill you
