Ignoring just about any bonus except sometimes Gallia and Asia will get you killed quite fast. Try ignoring Hispania and u will quickly meet a stack of 40-50 and get overrun.
It depends on how many picks you have. With 3v3 or more and 3 picks per player i agree - you shouldn't ignore anything. But playing 1v1 with 3 picks? You can't control everyting and you will surely won't leave parhta.
Counter picking is a big part of Warlight play so i have to disagree with you on this. You cannot expect that u just pick somewhere and expand and win without trying to predict your opponents move and pick and counter them.
Alright, but let's imagine you look at the map and you see nice pick combination (let's call it A). You analyze it and you notice, that it can be easily countered by combination B. So you want switch to B, but it's not that good as B can be countered by C. Unfortunatley, comparing to first combination (A), C is bad. So we have A < B, B < C, C < A. There's no difference between choosing one of it and and playing papper-rock-scissor game.
But to be clear - it's not map issue, but it's strictly related to settings.
