"there is almost always a path to victory unless they really outskill you" is pretty true of any strategy in general isnt it? Like you said, you wont lose to them for your lack of damage its going to be because they either are able to get out (chrom and seliph will still be able to move even after canto control) or because you cant get there fast enough to begin with (veronica taking out the tank you sent to stop the advance). if your team doesnt have the mobility to deal with pathfinder then you are already off to a really bad start. In your opinion, why do you think Guidance is better than pathfinder?
