The thing is, no matter how low someone shoots their IAFBs you can duck them and move in slowly. GL has a great walk speed which means getting in is actually way easier for him than certain chars with terrible walk speeds and far dashes that get caught by the next IAFB.
I'm not sure if you're an MK player but avoiding IAFBs the same way in that game was something you had to do VERY often. If you want a great example look at DJT vs REO, PL, or DetroitBalln in this year's Evo MK9 Top 8. If we play the cyborg match like that, it will be boring a require a lot of patience, but we technically shouldn't be getting hit by any fireballs (unless he uses meter to get himself like 2% chip)
