Petros can team with Mirah, or Mazir that still speed up COF. Plus Petros Volcano burn will rip all tanks infront of him as well as group them all together for an easy kill plus stuns. Vulko in HOL at high level is not used at all. Even thought Petros is buffer in HOL his damage out put is still higher vs Vulko and he doesnt die as fast as vulko. So again he accumulate more damage to that of vulko. Petros and vulko are are both equally good I can use either or in Arena. Except for one thing Petros will out last vulko in arena and 1vs1 at the end Petros always win that fight lol.
There is no petros or Vulko in the topscores of the hol teams at level 100 aka both are garbage for hol.
When it comes to pvp at level 100 Petros is in 95% of the top teams 10. Vulko is falling off because with all the frontliner teams he hardly does anything.
When it comes to CoF, petros is garbage, malrath is THE best tank for CoF hands down... petros doesnt regain enough health and if youre on a server where everyone has a petros, your petros will last like 2 fights.
So saying once more that it all comes down to arena and then Petros win it from Vulko by a landslide.
