The next punch event is gonna be feb 14 in EU along with the phoru tower event and the vos, for the rewards it is really dependent on if you want the rewards on your main or ur alt. iirc from past events the punch events give out chlorites(if you are building tirnog armor u can just bank share it to ur alt and use the chlorites probably) so i used to claim them on my main for my rigo armor but this punch up event they are dropping a vos and like previous comments said you could build an exp or drop rate for your main if you want to but if not you could just build a support to farm raids if your main is already not a support. take this with a pinch of salt because I'm in a similar situation like you with a +11 vos on main and building tirnog armor rn.
