Most issues I had were with experienced players -- I'm talking about players in clans and long-timers.
I find in general it's those that can cause you the most hassle but rather indirectly. The obvious noobs and people who really bring your squad down are easily kicked and it's very easy to justify kicking them out. But when you have a guy who regularly uses VOIP who sticks with the squad for the most part it gets very, very difficult to deal with them.
I find that this manifests by them taking their time while moving towards you or doing something wierd. I'd estimate 50% of my problems as SL are somewhat decent/average players who hang back and refuse to move up to you quickly. Me and 2 guys will typically be moving ahead and get into some cover only for me to check the map and see them about 100m-200m back behind us. And it's not like we're under fire or even moving that carefully. They're just painfully slow. Sometimes it only takes one or two calls of "Hey get over here, it's clear, move up" and other times I've had to yell at them for 2 minutes straight.
Strangely enough telling them I'll kick them makes them seriously get moving towards me.
Alternatively a lot of problems are caused by otherwise good players doing something retarded. This is usually taking a kit that we don't need, mainly HAT. I've seen a guy take HAT, get told by me to not take it in future without dying, accepts that he won't take it and then die only to take it again 2 minutes later.
I find that as an almost exclusively pub player I have to have an incredibly high tolerance for hijinks and bad playing. Any of you guys that tend to stick with people you know have no idea how stressful sorting out a pub squad into something resembling a fighting force is, let alone actually leading them successfully. Thank god for players like Bloodace who made things so much easier for me earlier.
One thing that has been mentioned here is the importance of good players in squads. I know the difference between leading an experienced squad and leading an incompetent squad. The experienced one will annihalate all opposition to such a degree it feels cruel. The incompetent one will lose battles from prepared positions, get killed by a lone wolf or kill zero enemies in a typical firefight. Sadly for me about a third of the time I play, the squad is incompetent.
I seem to have gone on a tangent leading into a tangent here. Good day.
