Another one of these questions...

Tyrant vs. Gladiator...

They both seem to be just about the same class... but correct me if I'm wrong, it seems like Tyrant dies quicker, but deals more damage.

Which does more damage, which dies quicker, which is going to be more geared towards PvP as of C5 ...

And most importantly... where in the world do you see the C5 updates... I just can't seem to find it.

Well, tyrant is FASTER then gladi, it got more atack speed and run speed.
Also, there is no oficial info on C5 yet, people read from korean and what ever other web sites and translate it. Also there are allot of C5 info here (http://www.l2guru.com/forum/forumdisplay.php?f=28) .
