I don't remember the guild saying you could dodge bullets as a rule, if anything the conversation was surrounding how guns are OP, and they would be if it wasn't for the fact that your character is heavily blast resistant and therefore on a tier level where the speed of bullets is inconsequential.

My Mech is powerful because it has computerized targeting systems, making a 'dodge' in a conventional sense difficult for anything but the fastest opponents, but it is more than balanced out by your character's ability to sponge high ordinance, which is comparatively much stronger than my mech's durability.

In future just stand behind something, or make something in front of you, if you don't want to get shot while standing out in the open. Even a T2 sniper would have a decent chance of hitting you in those circumstances.

If you think I'm out of line in saying your dodge wouldn't work against my bullets though feel free to ask Judge Rilla, as this is a ranked battle.
