Does luck directly depend on number of nodes in the network? If so, then it is more profitable to create more nodes than to have more proof of work! So, in this way those who can allocate a lot of IP addresses and attach a lot of mining nodes has more chances to win a block! If that is the case, then pool pressure can become high, because usually servers and ISP's has many more connections than a typical, client-only user. Sooner or later all such users will have to join some server, just to increase their luck.

I don't think so. It seems that new projects have a lot of hashrate at the beginning and later it drops when users are selling those coins for Bitcoins. So if you want to have many coins, it may be profitable to start later, when difficulty will be lower and price will drop. Of course I may be wrong, but I saw such things on many other altcoins and here it seems to follow the same path.
