Hey there. Yeah I'll agree with Elindor that players' experience in LiF is totally dependent on the group they join. For YO servers specifically, I'd say more than 90% of whether or not players have a good experience depends on the server they play on.
I'd suggest thinking about what kind of play-style you might enjoy. There is everything from from friendly RP oriented guilds to hardcore PvP groups planning on the MMO and getting organized now during the closed tests.
Shameless plug: If you're looking for some friendly fair-play groups, I'd suggest having a look at my post here:

Best of luck.
