Well, that is if the gank works out fine. Any mess ups and they just get more of your gold in addition to you losing time. The example with AP doesn't apply with all mids. Many of them will still require just as much careful timing (so the cd on their abilities is 6 seconds not 8, if they miss they still have close to nothing they can do) and aiming to take advantage of their stuff.Aircross said:LoL actually snowballs harder than DotA/Dota 2.eventhorizon525 said:le snip
Everything in LoL scales while very few abilities in Dota 2 scale. Feed a Queen of Pain 4 kills and Scream of Pain is not going to do any more damage than what it's hard coded to do, and Scream of Pain's cooldown never changes. Feed an AP mid 4 kills and their abilities will be hitting harder and more frequent thanks to Ability Power, Cool Down Reduction, and Magic Penetration.
The stat per gold ratio for items in DotA decreases as item tier increases while stat per gold ratio for items in LoL increases as item tier increases: http://forums.anandtech.com/showpost.php?p=34288821&postcount=4011
Gold loss on death is actually a mechanism that can prevent snowballing. The enemy's carry getting a little too much farm? Well, gank him/her several times and she won't be able to farm his/her items.
Also, just based on what I've seen of both DotA 2 and LoL, while LoL may technically (depending on view) be easier to snowball in, I've seen teams come back from the brink a lot more often in LoL. Unless the player is really skilled (at which point they'd probably win anyway), a fed player is often a lot more risky and daring making it very easy to punish (though that is really just human nature in a lot of cases).
