i play dota 1 for a long time. love it.
i play HON when its introduced until they stop letting SEA player to play and flying spaghetti monster still no HON yet at that time. love HON too.
i play LOL for a few months. Not enjoy it. i spends months hoping there is something will caught my interest, but nope.

Finally got dota 2 beta invite. never play a single match of Dota1 or HON or LOL after that.
The ping is great, less bug, consistent up time, constant improvement, balance and many more.
