Function of every tank

When Lineage 2 has not been GoD,every tank have their function in some places. For example,paladin and tk are excellent in partys,sieges and raids. In counterpart dark avenger and sk are excellent in pvp. Now in GoD is good to know if that functions still in every tank,caused my first char was paladin,i prefer to be a shinning knight over a dark knight but last time i decide to play dark avenger and today is a shinning sigel hell knight. Some people said that is the bad guy but see the movie HELLBOY,the main actor is the good guy beign bad guy. Well,im not to talk about this fact. I need to know if im a sigel hell knight i have advantage in pvp like dark avenger in ancient lineage 2,caused some time ago i think this,white tanks for partys,raids and sieges and dark knights for pvp,this fact still in actual tanks???? In other words,if a sigel phoenix knight and a sigel hell knight are on,which u pick for a raid,siege or party??? (and kartia and other things???)
