The Beginning. Since I can remember, I first judged someone based on their level of combat. This gave me an indication of whether they were a skilled player that could assist me or someone I could speak to. In the moment, I wasn't an expert in combat. I had no idea the meaning of Rune Armour was and I didn't know that their cape was a Legend's Quest purchase and use. I had no idea about any of that and all I could think was "Wow 27 combat nice!" Seriously!
Divergent types of people. As I grew, I began to know the Skillers, the Pures Combaters, Merchanters, and Forum/Player Moderators. Skillers may have high levels of experience and have good levels, but they cannot being below the level of 70. To solve this, I learnt of the outfits; the nice capes they were wearing were actually Skillcapes that required the level 99 skill to obtain one! These capes were very respected by me when I was about 34.
Pures can possess a huge amount of combat experience as well as numerous stats like Strength and Ranged as well as Magic up to level 99. But, they could also be level 75 to 85. While I didn't find this to be very helpful, I do think it was unusual and unneeded. But, I still had to differentiate between Pures players and other players. This led me to examine two things: their names as well as the clothes they wore.
If their name was like'X mxrng3pk' (if this is your name, I'm sorry) and their level of combat was quite low, I was able to separate them as a possible pure. After reviewing their clothes I concluded that they might be pure if it was Ranged or alching gear.
Combaters are those players who put more emphasis on the combat stats and less on the stats of skill. While they might be at the same level as an experienced player, combaters have 500-600 less overall levels. They also may not possess the same knowledge and skills. I discovered a magical place called hiscores that could aid me in solving my problem. I was aware of the statistics of the player now I could tell whether they were a skilled pure or a combater or a normal balanced player.
