Why so slow?

It's actually better with lower amount of points. You will enter only the games you really want, not all on your sight. This will increase an average odds of winning for everyone.

(for second question)It was the Dota 2 thing. They were being flooded, giving us loads of points.

Not only do they give less points but they aren't being made anymore it seems lol.

Why not.

I am most of the time on 300 points, what do you do with the points - are you eating them? I am not entering games I don't wanna play so I have much more points than I need. In fact people are winning games which they will never play because of so many points - that's sad...

Unless you check every few hours, points come back fast enough.

Now, don't be hasty, master Meriadoc.

Slow?! Rarely does a day start when I'm not at 300 points. That said I don't really enter very often any more. Only for games that I particularly want and only if I feel I have a reasonable chance of winning. Heck even giveaways that do conform to these conditions I'll often not enter anyway. I'm not sure why. Perhaps I start to feel that other people would appreciate the game more than me. Besides, I have enough games that I never have the time to play, no real use building up my Steam library any more than it is without the prospect of actually being able to work my way through it.
