If you think you spend too much time redeploying, you probably are dying too much. For all other concerns, I recommend taxiing yourself and skipping on the redeploy time altogether.
yeah, let's not promote more bailing to protect kd. As above, either taxi yourself...or deal with the mechanic that is there to help prevent certain things to some degree. ATV's are cheap ^.^
Or the jerks that jump out of a bad situation when they're cornered or outplayed just so they can pad their K/D ratio. Bunch of that going on lately. Get outmaneuvered in infantry? Redeploy. Get shot down in your aircraft? Bail and redeploy mid-air. Get your pretty little tank smashed by a more tactically-minded player? Bail and redeploy. I'm sure you can see a theme here...
