so if a lvl150 player vs a 150lvl can make e.g. 1200VP, a lvl145 vs lvl150 can not get more than, lets assume also 1200*, that which means that a lvl145 vs 145 can only do less VP than 1200 or the VPs are capped at a certain value, 1200 here. in first case that value would be of interest and/or if there is now a cap towards the max VP a lvl150 player can get (in this case the 1200VP).
it has to be something like that s.t. the description can hold. or lvl150 get significantly more bonus VP from chests, but this should not be considered here.
*but still if it would be the equal value a 150 can make it would be better to have a lower lvl then max. bc this lvl150 player can only get less points from you in return. and therefore there is still an incentive to stay below max level, but maybe this isnt addressed now and they just wanted to fix that a lower lvl cant make more VP then max lvl. either by a cap or bc that even fighting the exactly same lvl will also give less VP with decending lvl
