Yoott: you know whats really cool..... just because your a tier 6 in a tier 8 battle does not mean your supposed to be the one to take out the tier 8's...... theres are also tier 8s on your team... follow hem.... support them..... track down the enemy tier 6's..... or you can just run in suicide scream cry whine and complain and then come to the forums and do it as well...
L2Play.... L2Shoot.... L2Flank...L2Support..... just learn how to play
