As a player, I am kind of experienced, I've read through 3.5 basic rules a few times, Pathfinder a few more times, While with 5e I've read it multiple times. As such, I won't be asking to much rule questions unless I believe there have been some mistake or when I need to understand house rules.
I value Roleplaying above combat, but I also feel that too much of it is kind of boring. In combat I am quick to know when it is my turn and usually act rather fast.
My interaction with other players is usually that I try to understand my fellow players before I act and behave accordingly. I am ok with taking charge if I feel that we are getting nowhere due to indecision, but I don't believe that one must have a leader, I just don't like it when a group is stuck for longer than 30min trying to come up with a plan to enter a simple room which there might or might not be any threat.
