Historically, comp combos were more important than the map. There were very few maps where it forces a particular style of play. On a rare occasion did people mix things up, but in most cases they stuck with the combo synergies.
I don’t think this is a huge deal to be honest and for the regular player I think its better to enable all heroes to be viable on all maps. We have minor variations and such, but for the most part playing well trumps combos.
