Lately I've tried getting into the habit of not using Drive Cancels in the corner, because it feels like for every hit-confirm in the corner, you can do a non-drive variant and get close in damage (only about 30-50 less). I've been using Drives mostly to turn EX Trap Shots into about 250 damage / corner escapes, and getting damage off a combo that corner carries but didn't start in the corner.
