BWii needs more than just decent shooting controls, it also needs "go there" orders and better ways to handle split forces. Currently they all want to follow you in a giant clusterfuck instead of letting you, say, keep the arty behind without it wanting a hug from you every time it kills its designated target.
This is interesting cuz I'm assuming you haven't played the first game. You probably don't know what it was like to not have pointer control while running. Walking, aiming, and lock-on are right out of Metroid Prime... and I'm sure you'd be happy to lock-on ONLY to the closest object in front of you every single time. Lock-on w/ Pointing is fine in BWii cuz I'm constantly changing targets to lock onto and telling my units to chase things. In BWi I had to RUN TO TARGETS or manually aim while stationary to get a desired lock. I use lock-on maybe half the time in BWii when manually shooting things (the secret to maximizing efficiency and stomping Flames of Chaos on VS. Melee mode).
My two burning frustrations with BWii were the omissions of:
1. Big open-area missions/maps as opposed to linearly-progressed trails, and
2. Manually ordering units to stand at specific ground locations you aimed at (that's right, aim at the ground, "go there", done!)
That made me SAD. In Battalion Wars, No.1 were my favorite type missions (figure out your own approach/path), and No.2 was important for doing No.1!!! And now theyre gone D=
KDR, in the Options Menu you can disable your units from following you after they kill something, if that helps. That's how it worked in the first game. (I stopped disabling Auto-Follow due to BWii's linear level design; moving quickly as a massive pack is critical to saving time for score reasons).
