Bro, I give you some good advise. Ditch the freerolls and try some cash game. Especially playing Omaha the players are so soft it's amazing! My last 2 or 3 sessions were so easy. They sometimes play like they have never played Omaha before, calling big bets with nonsense like 1 or 2 pair while there are flushes, straight and boats possible.
Sure sometimes you get a bad beat here and there but in the long run against such weak competition it should be easy to get a decent profit, trust me!
Freerolls are just lottery basically but if you have some good poker skills then give it a shot and thank me later.
