Party 100$ NL 6-max question.

[DrLAXLAX]

Hi.

I am relatively new to partys 100$ 6-max, I usualy play at other site. After few sessions I got some very unusual in my view impresions.
1. Almost every pot is raised. And every second re-raised. Is this usual party play at that level?
2. One guy raises other calls flop is J74 rainbow first bets pot other calls, same on turn. On river first guy go allin (pot about 70$) 130$ and other calls with pair of fours . First shows AK ( Ace high). (Final pot is about 270$). Is such things often there???
I am a tight (may be too tight) player but felt like everyone plays there for fun and it can be costly when your re raise is called by 5 players..
Some suggestions?
