press the attack/on hits is king on new pantheon
PTA gives you the burst you need conqueror gets turned on too late since his combat goes favorably like (W enemy + 3 stacks shield bash + 4 stack auto attack is 5 finish with Q thats where conqueror's "magic" happens is most effective point after that theres no more moves you can do.
press the attack however it allows you to do your favored trade style and proc press the attack burst then Q then retreat with shield wall. you did your damage at that point and to add to this your teammates can profit off this damage also which makes sure you dont really fall off. bork/
or
is great on pantheon due to his W can activate on hits. if your going ravenous get deaths dance.
i can carry harder in my games but i cant end since ughhhh teammate iq limitation. those situations where your teammates not end or flat out feed/throw.
(havent tested) klepto is nice vs unwinnable lanes since you can use W to make that money then sustain.
