GAC matchmaking after Hyperdrive Bundle

Hi guys, I am lvl 82 and thinking of getting the hyperdrive bundle but concerned about Grand Arena matchmaking.

Will I be outmatched by those that have more focused rosters after I buy the bundle?
How long does it take to 'outgrow' the 'bloat' for the hyperdrive bundle as far as GAC is concerned?

Those that have experience please share it that would be helpful.

Thank you.
