More explorable planets in new ME,or a liniar touch like in ME2?

I have to be honest but I got sick of the same dead worlds in ME1 with a tank that handles like a drunk rhino after the 2rd playthrough, there were/are only so many times that a dead world is going to look "cool" before it just gets old and boring. The main worlds in MEA always feel different every time new places to find new quests to complete, and etc.

Now I love the Nomad in MEA. Who need guns when I could run over things and crash into enemies at 140 MPH in 4 or 6 wheel drive? Which for me personally, is a lot more fun than shooting them (although that is fun too).

The idea solution for me would rather a have a mix of say 3-5 large hub worlds and maybe 5-10 smaller worlds (as long as they're all not all the same dead boring lifeless worlds like those in ME1) that I can travel by foot, the Nomad, a weaponized version of the Nomad, a hoverbike, a small one-person scout airship, and a deep sea diving mech, and a small sailing ship. That I can use for various missions ranging from storming an enemy compound, stealth, recon, search and destroy, rescue missions, to resource gathering, to going on a date with a LI, to just traveling around just for the hell of it aka you know for fun. Depending on story requirements, personal gameplay styles, and just good ole personal preferences (some may want to storm the enemy compound, and others might want to use stealth) 

Now obviously some vehicles can only be used on/in certain worlds/environments (so you can't use a deep sea diving mech in a desert for example) and each should be upgraded to allow players to choose what they want from the vehicles (with stuff like weapons, armor, scanners, boosters, brakes, and so on) more than the just the paint job.
